  - input number: holding [-]/[+] buttons could increase the step speed non-linearly (or user-controlled)
  - input number: use mouse wheel to step up/down
  - input number: non-decimal input.
+ - input number: display and input as hexadecimal
+ - input number: applying arithmetics ops (+,-,*,/) messes up with text edit undo stack.
  - text: proper alignment options
  - layout: horizontal layout helper (#97)

  - plot: "smooth" automatic scale over time, 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
- - inputfloat: applying arithmetics ops (+,-,*,/) messes up with text edit undo stack.
  - slider: allow using the [-]/[+] buttons used by InputFloat()/InputInt()
  - slider: initial absolute click is imprecise. change to relative movement slider (same as scrollbar).
  - slider: add dragging-based widgets to edit values with mouse (on 2 axises), saving screen real-estate.
