• Done
  • Check events only for interested widgets (use focus for keyboard and region for mouse)
  • Add handling of disabled widget nodes
  • Add handling of custom external actions for widgets
  • Do something with return of custom handlers (the exact same thing we do with event handlers)
  • Add scroll support
  • Add hstack/vstack containers
  • Improve input (keyboard) handling
  • Implement copy/paste
  • Add HiDPI handling
  • Handle window resize
  • Improve handling of Color (turn to 0.0 to 1.0 instead of 0 to 255? only do it for alpha?)
  • Add handling of non visible widget nodes
  • Handle widget fixed size
  • Add good looking caret to textField
  • Add support for onFocus/onBlur
  • Maybe we don't need this and we can get by with position in render function?
    • Add support for onEnter/onLeave (keep track of previous active widgets)
    • We probably need it for drag&drop
  • How is the user going to provide state updates?
    • We already provide this with the State monad and corresponding lenses
  • Improve mouse support/current state of mouse and keyboard for event handling
• Pending
  • Make handleEvent run inside MonadState (required to update user provided lenses)
  • Create layer widget to handle overlays/dialog boxes
  • How will long running (i.e., not immediate) user tasks will be handled?
  • Add text selection/editing to textField
  • Drag & drop (add attribute indicating if component supports being source/target)
  • Stop, think and design
    • How should all of this be organized?
    • How should modules be layed out?
    • What are good interfaces the different parts of the system?
    • Does it make sense that handleEvent is the only pure function in a widget?
  • Based on the previous design, refactor modules
  • Implement styling engine. Think why Maybe Double instead of Maybe Dimension (to handle pixels, percent, etc)
  • Check if advanced type level features would improve the design
  • Check what syntax extensions can be abused to make life easier
  • Does it make sense to avoid lenses internally, given that we already include the dependency?
  • Can we cache some drawing operations?
  • Can we use Skia? Does it make sense?
