Problem: Slow redrawing with DirectX.
Solution: Avoid calling gui_mch_flush() unnecessarily, especially when
updating the cursor. (Ken Takata, closes#2560)
Problem: Duplicated code for getting a typed character. CursorHold is
called too often in the GUI. (lilydjwg)
Solution: Refactor code to move code up from mch_inchar(). Don't fire
CursorHold if feedkeys() was used. (closes#2451)
Problem: balloon_show() only works in terminal when compiled with the GUI.
Solution: Add FEAT_BEVAL_GUI and refactor to move common code out of the GUI
specific file.
Problem: Mac features are confusing.
Solution: Make feature names more consistent, add "osxdarwin". Rename
feature flags, cleanup Mac code. (Kazunobu Kuriyama, closes#2178)
Problem: FEAT_WINDOWS adds a lot of #ifdefs while it is nearly always
enabled and only adds 7% to the binary size of the tiny build.
Solution: Graduate FEAT_WINDOWS.
Problem: MS-Windows: when 'clipboard' is "unnamed" yyp does not work in a
:global command.
Solution: When setting the clipboard was postponed, do not clear the
register.
Problem: When checking for CTRL-C typed the GUI may detect a screen resize
and redraw the screen, causing trouble.
Solution: Set updating_screen in ui_breakcheck().
Problem: When using ":sleep" channel input is not handled.
Solution: When there is a channel check for input also when not in raw mode.
Check every 100 msec.
Problem: The versplit feature makes the code uneccessary complicated.
Solution: Remove FEAT_VERTSPLIT, always support vertical splits when
FEAT_WINDOWS is defined.
Problem: The Sniff interface is no longer useful, the tool has not been
available for may years.
Solution: Delete the Sniff interface and related code.
Problem: The socket I/O is intertwined with the netbeans code.
Solution: Start refactoring the netbeans communication to split off the
socket I/O. Add the +channel feature.
Problem: On MS-Windows console Vim uses ANSI APIs for keyboard input and
console output, it cannot input/output Unicode characters.
Solution: Use Unicode APIs for console I/O. (Ken Takata, Yasuhiro Matsumoto)
Problem: ":tabdo windo echo 'hi'" causes "* register not to be changed.
(Salman Halim)
Solution: Change how clip_did_set_selection is used and add
clipboard_needs_update and global_change_count. (Christian
Brabandt)
Problem: Having CTRL-C interrupt or not does not check the mode of the
mapping. (Ingo Karkat)
Solution: Use a bitmask with the map mode. (Christian Brabandt)
Problem: Cannot wrap lines taking indent into account.
Solution: Add the 'breakindent' option. (many authors, final improvements by
Christian Brabandt)
Problem: Crash when putting zero bytes on the clipboard.
Solution: Do not support the utf8_atom target when not using an Unicode
encoding. (Naofumi Honda)
Problem: Crash and compilation warnings with Cygwin.
Solution: Check return value of XmbTextListToTextProperty(). Add type casts.
Adjust #ifdefs. (Lech Lorens)
