+Popup windows:
+- Implement flip option
+- Have a way to scroll to the bottom? (#4577)
+- Why does 'nrformats' leak from the popup window buffer???
+- 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 if it was the last one, 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?
+- Figure out the size and position better.
+    if wrapping splits a double-wide character
+    if wrapping inserts indent
+- When drawing on top half a double-wide character, display ">" or "<" in the
+  incomplete cell.
+- Use a popup window for the "info" item of completion instead of using a
+  preview window.  Ideas in issue #4544.
+  How to add highlighting?
