@ -8,16 +8,12 @@ It's mostly a bunch of personal notes, probably incomplete. Feel free to query i
- doc/test: add a proper documentation+regression testing system (#435)
- doc/test: checklist app to verify binding/integration of imgui (test inputs, rendering, callback, etc.).
- doc/tips: tips of the day: website? applet in imgui_club?
- project: folder or separate repository with maintained helpers (e.g. imgui_memory_editor.h, imgui_stl.h, maybe imgui_dock would be there?)
- window: calling SetNextWindowSize() every frame with <= 0 doesn't do anything, may be useful to allow (particularly when used for a single axis). (#690)
- window: add a way for very transient windows (non-saved, temporary overlay over hundreds of objects) to "clean" up from the global window list. perhaps a lightweight explicit cleanup pass.
- window: auto-fit feedback loop when user relies on any dynamic layout (window width multiplier, column) appears weird to end-user. clarify.
- window: allow resizing of child windows (possibly given min/max for each axis?.)
- window: background options for child windows, border option (disable rounding).
- window: resizing from any sides? done. > need backends to honor mouse cursors properly. (#822)
- window: resize from borders: support some form of outer padding to make it easier to grab borders. (#822)
- window: fix resize glitch when collapsing an AlwaysAutoResize window.
- window: begin with *p_open == false could return false.
- window: get size/pos helpers given names (see discussion in #249)
- window: a collapsed window can be stuck behind the main menu bar?

- window: expose contents size. (#1045)
- window: using SetWindowPos() inside Begin() and moving the window with the mouse reacts a very ugly glitch. We should just defer the SetWindowPos() call.
- window: GetWindowSize() returns (0,0) when not calculated? (#1045)
- window: freeze window flag: if not focused/hovered, return false, render with previous ImDrawList. and/or reduce refresh rate.
- window: investigate better auto-positioning for new windows.
- window/opt: freeze window flag: if not focused/hovered, return false, render with previous ImDrawList. and/or reduce refresh rate.
- window/child: the first draw command of a child window could be moved into the current draw command of the parent window (unless child+tooltip?).
- window/clipping: some form of clipping when DisplaySize (or corresponding viewport) is zero.
- scrolling: while holding down a scrollbar, try to keep the same contents visible (at least while not moving mouse)
- scrolling: allow immediately effective change of scroll after Begin() if we haven't appended items yet.
- scrolling/clipping: separator on the initial position of a window is not visible (cursorpos.y <= clippos.y). (2017-08-20: can't repro)
