Changes / Issues / Fixes

• Release a mobile version with touch support
• Separate updateUI() function into updateBanner() and updateButtons()
• Remove style changes from setBrushColor()
• Fix button colors not updating
• Change origin setpoint to mousedown (instead of mouseup)
• Added custom mouse cursors
• Set indentation style to 2 tabs
• Add toggle function to hide/show keyboard map
• Add more variety: shapes, colors, brush width, etc. (experiment)
• Replace all HTML legacy tags with CSS

Desktop

• Expand mousemove listener to entire document body: wilder but more satisfying
• Add a button to toggle drawing mode
• Get actionListener working properly with mousemove and mousedown events (similar to mobile drawing)

Mobile

• Disable swipe down refresh gesture
• Needs more testing: limited testing done with Chrome device emulation and an S10+
