- combo: turn child handling code into popup helper
|
||||
- list selection, concept of a selectable "block" (that can be multiple widgets)
|
||||
- menubar, menus
|
||||
- plot: plot lines draws 1 item too much?
|
||||
- plot: add a stride parameter?
|
||||
- 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)
