@ -49,6 +49,7 @@ Other Changes:
rather than the Mouse Down+Up sequence, even if the _OpenOnArrow flag isn't set. This is standard behavior
and amends the change done in 1.76 which only affected cases were _OpenOnArrow flag was set.
(This is also necessary to support full multi/range-select/drag and drop operations.)
- Tab Bar: Hide tab item close button while dragging a tab.
- Metrics: Various tweaks, listing windows front-to-back, greying inactive items when possible.

- tabs: "there is currently a problem because TabItem() will try to submit their own tooltip after 0.50 second, and this will have the effect of making your tooltip flicker once." -> tooltip priority work

- tabs: while dragging/reordering a tab, close button decoration shouldn't appear on other tabs
- tabs: make EndTabBar fail if users doesn't respect BeginTabBar return value, for consistency/future-proofing.
- tabs: persistent order/focus in BeginTabBar() api (#261, #351)
- tabs: TabItem could honor SetNextItemWidth()?
