- filters: set a current filter that tree node can automatically query to hide themselves
- filters: handle wildcards (with implicit leading/trailing *), regexps
- shortcuts: add a shortcut api, e.g. parse "&Save" and/or "Save (CTRL+S)", pass in to widgets or provide simple ways to use (button=activate, input=focus)
- input: keyboard: full keyboard navigation and focus.
- keyboard: tooltip & combo boxes are messing up / not honoring keyboard tabbing
- keyboard: full keyboard navigation and focus.
- input: support trackpad style scrolling & slider edit.
- tooltip: move to fit within screen (e.g. when mouse cursor is right of the screen).
- misc: not thread-safe
- misc: double-clicking on title bar to minimize isn't consistent, perhaps move to single-click on left-most collapse icon?
- style editor: add a button to print C code.
