  * TODO:
  * - Add a way to set the 16 ANSI colors, to be used for 'termguicolors' and in
- *   the GUI.
+ *   the GUI. #2747
  * - Win32: Make terminal used for :!cmd in the GUI work better.  Allow for
  *   redirection.  Probably in call to channel_set_pipes().
  * - implement term_setsize()
  * - Copy text in the vterm to the Vim buffer once in a while, so that
  *   completion works.
- * - Adding WinBar to terminal window doesn't display, text isn't shifted down.
- *   a job that uses 16 colors while Vim is using > 256.
  * - in GUI vertical split causes problems.  Cursor is flickering. (Hirohito
  *   Higashi, 2017 Sep 19)
  * - after resizing windows overlap. (Boris Staletic, #2164)
