@ -81,6 +81,9 @@ Other Changes:
- Amended context menu right-click opening code to check that the right-click
hasn't been owned by another items. This is more correct and also necessary
to avoid Drags/Sliders cancelling also triggering a cancel menu. (#8564, #9534)
- ImGuiTextFilter:
- Added `DrawWithHint()` function. (#6206, #6395, #6447)
- Added a "incl,-excl" hint by default when the search field is empty. (#6206, #6395, #6447)
- Style:
- Inverted `ImGuiCol_TitleBgXXX` colors for `StyleColorsLight()` so that the selected
window title bar appears brighter.
