- 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)
- clipper: ability to force display 1 item in the list would be convenient.
- clipper: ability to run without knowing full count in advance.
- splitter/separator: formalize the splitter idiom into an official api (we want to handle n-way split) (#319)
@ -156,6 +157,7 @@ It's mostly a bunch of personal notes, probably incomplete. Feel free to query i
- text: proper alignment options in imgui_internal.h
- text wrapped: figure out better way to use TextWrapped() in an always auto-resize context (tooltip, etc.) (#249)
- text: it's currently impossible to have a window title with "##". perhaps an official workaround would be nice. \ style inhibitor? non-visible ascii code to insert between #?
- tree node / optimization: avoid formatting when clipped.
- tree node: tree-node/header right-most side doesn't take account of horizontal scrolling.
@ -215,6 +217,7 @@ It's mostly a bunch of personal notes, probably incomplete. Feel free to query i
- keyboard: full keyboard navigation and focus. (#323)
- focus: preserve ActiveId/focus stack state, e.g. when opening a menu and close it, previously selected InputText() focus gets restored (#622)
- focus: SetKeyboardFocusHere() on with >= 0 offset could be done on same frame (else latch and modulate on beginning of next frame)
- focus: unable to use SetKeyboardFocusHere() on clipped widgets. (#343)
- inputs: rework IO system to be able to pass actual ordered/timestamped events. use an event queue? (~#335, #71)
- inputs: allow to decide and pass explicit double-clicks (e.g. for windows by the CS_DBLCLKS style).
- inputs: support track pad style scrolling & slider edit.
