@ -67,6 +67,7 @@ It's mostly a bunch of personal notes, probably incomplete. Feel free to query i
- widgets: selectable: generic BeginSelectable()/EndSelectable() mechanism.
- widgets: selectable: a way to visualize partial/mixed selection (e.g. parent tree node has children with mixed selection)
- widgets: checkbox with custom glyph inside frame.
- widgets: IsItemEdited() on InputScalar keeps returning true because InputText vs formatted output are mismatched.
- input text: clean up the mess caused by converting UTF-8 <> wchar. the code is rather inefficient right now and super fragile.
- input text: reorganize event handling, allow CharFilter to modify buffers, allow multiple events? (#541)
