 When the screen scrolls up for output of an Ex command, popups move too, so
 that they will not cover the output.
 
+The current cursor position is displayed even when it is under a popup window.
+That way you can still see where it is, even though you cannot see the text
+that it is in.
 
 
 
 IMPLEMENTATION:
-- buffers remain after a popup was deleted.
 - Why does 'nrformats' leak from the popup window buffer???
+- Option to set first line to display (useful for a preview window)
+- Disable commands, feedkeys(), CTRL-W, etc. in a popup window.
+  Use NOT_IN_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?
+- When selecting text in the popup with modeless selection, do not select
+  outside of the popup and don't select the border or padding.
+- Allow the user to drag the popup window when the "dragging" property is set.
 - Make redrawing more efficient and avoid flicker:
     - put popup menu also put in popup_mask?
-- Disable commands, feedkeys(), CTRL-W, etc. in a popup window.
-  Use NOT_IN_POPUP_WINDOW for more commands.
 - Invoke filter with character before mapping?
 - Figure out the size and position better.

+- When drawing on top half a double-wide character, display ">" or "<" in the

 - Can the buffer be re-used, to avoid using up lots of buffer numbers?
 - Implement all the unimplemented options and features.
