  - combo: turn child handling code into popup helper

  - plot: "smooth" automatic scale, user give an input 0.0(full user scale) 1.0(full derived from value)
  - plot: add a helper e.g. Plot(char* label, float value, float time_span=2.0f) that stores values and Plot them for you - probably another function name. and/or automatically allow to plot ANY displayed value (more reliance on stable ID)
  - file selection widget -> build the tool in our codebase to improve model-dialog idioms (may or not lead to ImGui changes)
  - slider: allow using the [-]/[+] buttons used by InputFloat()/InputInt()
- - slider: initial absolute click is unprecise. change to relative movement slider? hide mouse cursor, allow more precise input using less screen-space.

  - 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)
  ! keyboard: tooltip & combo boxes are messing up / not honoring keyboard tabbing
  - keyboard: full keyboard navigation and focus.

  - 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 output C code.
