@ -126,9 +126,10 @@ Other Changes:
- TabBar: Fixed unfocused tab bar separator color (was using ImGuiCol_Tab, should use ImGuiCol_TabUnfocusedActive).
- Columns: Fixed a regression from 1.71 where the right-side of the contents rectangle within each column
would wrongly use a WindowPadding.x instead of ItemSpacing.x like it always did. (#125, #2666)
- Columns: Improved honoring left-most and right-most alignment with various values of ItemSpacing.x and
WindowPadding.x. In particular, the right-most edge now reaches up to the clipping rectangle while
ensuring that the right-most column clipping width matches others. (#125, #2666)
- Columns: Made the right-most edge reaches up to the clipping rectangle (removing half of WindowPadding.x
worth of asymmetrical/extraneous padding, note that there's another half that conservatively has to offset
the right-most column, otherwise it's clipping width won't match the other column). (#125, #2666)
- Columns: Improved honoring alignment with various values of ItemSpacing.x and WindowPadding.x. (#125, #2666)
- Word-wrapping: Fixed overzealous word-wrapping when glyph edge lands exactly on the limit. Because
of this, auto-fitting exactly unwrapped text would make it wrap. (fixes initial 1.15 commit, 78645a7d).
- Scrolling: Added SetScrollHereX(), SetScrollFromPosX() for completeness. (#1580) [@kevreco]

// Have the Item Picker break in the ItemAdd() function instead of ItemHoverable() - which is earlier in the code, will catch a few extra items, allow picking items other than Hovered one.
// This adds a small runtime cost which is why it is not enabled by default.
