@ -64,6 +64,8 @@ Other Changes:
- 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).
- Columns: Made GetColumnOffset() and GetColumnWidth() behave when there's no column set, consistently with
other column functions. (#2683)
- Scrolling: Added SetScrollHereX(), SetScrollFromPosX() for completeness. (#1580) [@kevreco]
- Style: Attenuated default opacity of ImGuiCol_Separator in Classic and Light styles.
- Style: Added style.ColorButtonPosition (left/right, defaults to ImGuiDir_Right) to move the color button
