 TODO:
 - Why does 'nrformats' leak from the popup window buffer???
+- When the lines do not fit show a scrollbar (like in the popup menu).
+  Use the mouse wheel for scrolling.
 - Disable commands, feedkeys(), CTRL-W, etc. in a popup window.
   Use ERROR_IF_POPUP_WINDOW for more commands.
 - Add 'balloonpopup': instead of showing text, let the callback open a popup
   window and return the window ID.   The popup will then be closed when the
   mouse moves, except when it moves inside the popup.
 - For the "moved" property also include mouse movement?
+- Can the buffer be re-used, to avoid using up lots of buffer numbers?
+- Have an option to attach the popup to a text position, like text properties
+  do. (#4560)
 - Make redrawing more efficient and avoid flicker:
     - put popup menu also put in popup_mask?
 - Invoke filter with character before mapping?
