@ -108,9 +108,12 @@ Other Changes:
- Added GetBackgroundDrawList() helper to quickly get access to a ImDrawList that will be rendered
behind every other windows. (#2391)
- Nav: Fixed a tap on AltGR (e.g. German keyboard) from navigating to the menu layer.
- DragScalar, InputScalar, SliderScalar: Added support for u8/s8/u16/s16 data types.
We are reusing function instances for larger types to reduce code size. (#643, #320, #708, #1011)
- Nav: Fixed a tap on AltGR (e.g. German keyboard) from navigating to the menu layer.
- Nav: Fixed Ctrl+Tab keeping active InputText() of a previous window active after the switch. (#2380)
- Fixed IsItemDeactivated()/IsItemDeactivatedAfterEdit() from not correctly returning true
when tabbing out of a focusable widget (Input/Slider/Drag) in most situations. (#2215, #1875)
- InputInt, InputFloat, InputScalar: Fix to keep the label of the +/- buttons centered when
style.FramePadding.x is abnormally larger than style.FramePadding.y. Since the buttons are
meant to be square (to align with e.g. color button) we always use FramePadding.y. (#2367)
@ -123,9 +126,14 @@ Other Changes:
when manipulating the scrollbar of a multi-line input text.
- ColorPicker: Fixed a bug/assertion when displaying a color picker in a collapsed window
while dragging its title bar. (#2389)
- MenuItem, Selectable: Fixed disabled widget interfering with navigation (fix c2db7f63 in 1.67).
- TabBar: Fixed a crash when using BeginTabBar() recursively (didn't affect docking). (#2371)
- TabBar: Added extra mis-usage error recovery. Past the assert, common mis-usage don't lead to
hard crashes any more, facilitating integration with scripting languages. (#1651)
- Text: Fixed large Text/TextUnformatted call not declaring its size when starting below the
lower point of the current clipping rectangle. Somehow this bug has been there since v1.0!
It was hardly noticeable but would affect the scrolling range, which in turn would affect
some scrolling request functions when called during the opening frame of a window.
- Plot: Fixed divide-by-zero in PlotLines() when passing a count of 1. (#2387) [@Lectem]
- Log/Capture: Fixed extraneous leading carriage return.
- Log/Capture: Fixed an issue when empty string on a new line would not emit a carriage return.

- image/image button: misalignment on padded/bordered button?
- image/image button: parameters are confusing, image() has tint_col,border_col whereas imagebutton() has bg_col/tint_col. Even thou they are different parameters ordering could be more consistent. can we fix that?
- image button: not taking an explicit id is odd.
- slider/drag: ctrl+click when format doesn't include a % character.. disable? display underlying value in default format? (see InputScalarAsWidgetReplacement)
- slider: allow using the [-]/[+] buttons used by InputFloat()/InputInt()
- slider: initial absolute click is imprecise. change to relative movement slider (same as scrollbar). (#1946)
- slider: add dragging-based widgets to edit values with mouse (on 2 axises), saving screen real-estate.

- text wrapped: figure out better way to use TextWrapped() in an always auto-resize context (tooltip, etc.) (#249)
- text: it's currently impossible to have a window title with "##". perhaps an official workaround would be nice. \ style inhibitor? non-visible ascii code to insert between #?
- text: provided a framed text helper, e.g. https://pastebin.com/1Laxy8bT
- text: refactor TextUnformatted (or underlying function) to more explicitly request if we need width measurement or not
- text link/url button: underlined. should api expose an ID or use text contents as ID? which colors enum to use?
- tree node / optimization: avoid formatting when clipped.
@ -246,7 +248,7 @@ It's mostly a bunch of personal notes, probably incomplete. Feel free to query i
- log: let user copy any window content to clipboard easily (CTRL+C on windows? while moving it? context menu?). code is commented because it fails with multiple Begin/End pairs.
- log: obsolete LogButtons() all together.
- log: LogButtons() options for specifying depth and/or hiding depth slider
- filters: set a current filter that tree node can automatically query to hide themselves
- filters: handle wild-cards (with implicit leading/trailing *), reg-exprs
- filters: fuzzy matches (may use code at blog.forrestthewoods.com/4cffeed33fdb)

- font: finish CustomRectRegister() to allow mapping Unicode codepoint to custom texture data
- font: PushFontSize API (#1018)
- font: MemoryTTF taking ownership confusing/not obvious, maybe default should be opposite?
- font: storing MinAdvanceX per font would allow us to skip calculating line width (under a threshold of character count) in loops looking for block width
- font/demo: add tools to show glyphs used by a text blob, display U16 value, list missing glyphs.
- font/demo: demonstrate use of ImFontGlyphRangesBuilder.
- font/atlas: add a missing Glyphs.reserve()
