What’s New on Polypad

### January

- New floating action bar with many new ways to customise tiles.
- Logic gates, switches, lightbulbs, latches and flip-flops for learning computer science.
- New help and support panel accessible from the right settings panel.
- Advanced option to hide the resize or customise handles for specific tiles.
- Improved units and labels for geometry utensils, including inches for the ruler.
- Split larger number tiles first into individual row, then individual tiles.
- Many bug fixes and performance improvements.

### December

- Chessboard and pieces, including move hints.
- Ten frames and two-sided counters.
- Multiple-jump arrows for number line.
- Handle to resize the plates of the balance scales, and better highlight when other tiles intersect with the target areas.
- Link tables to coordinate axes to scatter-plot data. Double-click on function plots or series to change their colour.
- Link the same component (e.g. table or equation) to multiple other tiles (e.g.charts or coordinate systems).
- Improved parsing of equations involving implicit multiplication or mixed numbers.
- Rich text keyboard shortcuts.

### November

- New compass and set triangle utensils.
- Sliders for variables that can be used in equation or coordinate system plots. Significantly improved function plotting.
- Option to "evaluate" equations on the canvas. Use equation as weights on the balance scale.
- Action to "transpose" a table.
- Optional sound effects for many actions like rolling dice or shuffling cards.

### August

- Support for 3D geometry: add some built-in solids to the canvas, or create custom nets using polygon tiles. Polyhedra can be rotated
- Many different chart tiles (row, column, line, area, pie, donut or box plot): you can data from any table to a chart, modify individual series by double-clicking, and choose from many different display options (e.g. stacked or grouped).
- New Clock components
- Improved graphic precision, and support for implicit multiplication in equation editor.
- High contrast mode for projecting Polypad in the classroom (enable in settings popup).

### July

- Significantly updated "File" menu: organise saved Polypads into folders, more granular sharing settings (public, students/teachers, private), examples and assignments appear as a special folder, and we moved the share and changelog panels.
- Re-organised "Tiles" sidebar with improved grouping of tile types.
- Buttons to change the denominator of fraction bars (expand and reduce), including support for denominators up to 1/24.
- New "Number Dot Arrangement" component.
- New number tables (addition, multiplication and integers) and number frame components.
- Remember the weight of balance scale tiles when you save a Polypad. Fix support for algebra tiles on the balance scale: you can now change the value of "x" and even solve quadratic equations.
- New algebra tiles for y, y² and xy, including support on balance scales.
- New advanced options to lock the position of a tile (but allow selecting/copying/etc) and to make a tile invisible.
- Improved change handling with the colour picker (create a single "undo" state when moving a slider or typing in the RGB fields).
- Updated number card colours, and action to "negate" their value.

### June

- Polyhedral Dice.
- Stack, shuffle and draw playing cards, standard deck template in sidebar.
- New "join" action to merge multiple polygons. Improved "cut" algorithm for polygons.
- Double-click dice, coins and spinners to randomise, and playing cards to draw a card.
- Tutorial Pages for every tile type.
- Improved numberline resizing and snapping, and flip actions for ruler and protractor.
- Significant performance improvements.
- Improved graph plotting with implicit functions.
- Hide Exploding Dots labels when the "hide number labels" option is selected.
- Pride Month background.

### May

- Transparency support in colour picker.
- Drag to select ranges of cells in tables, and copy/delete them.
- New Domino tiles under
*Probability*. - Irregular pentagons under
*Geometry*. - Handle to partially highlight fraction bars.
- Function plotting: create a coordinate system and an equation editor component. Next, drag the blue triangle on the right side of the equation editor onto the coordinate system. You can plot any expression with one variable, an equation of the form
*y*=f (*x*), an implicit function containing*x*and*y*, as well as polar functions of the form*r*=f (θ ). - Buttons to quickly change the axes scales of coordinate systems.
- Decimal and percentage labels for fraction bars and fraction circles. You can switch between the different display modes in the settings panel on the right.
- Direct number inputs for the RGB values in the colour picker.
- New table component in the
*Tools*section of the sidebar. - Layering and locking for tiles: enable
*Advanced Options*in the settings panel on the right. Then you can use the new options in the toolbar to force tiles to stay in the foreground or background, or lock tiles. To revert locking, click*Unlock All Tiles*in the settings panel. - Increased limit of saved Polypad canvases per account from 100 to 250.
- Equation editor improvements.

Keyboard Shortcuts and Accessibility

These are the keyboard shortcuts supported by Polypad for accessibility:

`SHIFT`

: hold while you click on multiple tiles to select all of them at once`ALT`

: hold before clicking and dragging on a tile to move a copy`BACKSPACE`

: delete your current selection`C`

: duplicate your current selection`CTRL/CMD`

+`X/Y`

: undo or redo your last change`ARROWS`

: move the currently selected tiles up, down, left or right (hold`SHIFT`

to reduce the shift size, for more precise moving)`R`

: rotate the currently selected tile by 15° (hold`SHIFT`

to rotate by –15°)`S`

,`D`

,`F`

: move the focus to the sidebar on the left, toolbar at the bottom or canvas area respectively`V`

,`P`

,`G`

,`T`

,`Q`

,`E`

: switch to the move, pen, geometry, text, equation or eraser tool`ESC`

: clear the current selection and close any open popups and modals`TAB`

: cycle through all buttons on the page and tiles on the canvas (hold`SHIFT`

to reverse direction)`SHIFT`

+`S`

: save the current canvas (if you are signed into a Mathigon account)

Use `CTRL/CMD`

+ `X/C/V`

to cut, copy or paste tiles. You can even copy and paste tiles from one canvas onto another!

Points and tiles will automatically snap to nearby shapes or gridlines as you move them. You can disable this behaviour by pressing the `SHIFT`

key while moving an item with your mouse or trackpad.
