 - Free-Form Select stamping/finalizing is incorrect when the selection is off-screen to the left or top.
 - Status bar description can be left blank when selecting a menu item. (I think the `Leave` event can come after closing, once the mouse moves.)
 - Menu items like Copy/Cut/Paste are not grayed out when inapplicable. Only unimplemented items are grayed out.
-- Set As Wallpaper may not work on your system. For me, on Ubuntu, the wallpaper setting is updated but the picture is not, unless I manually pick it. There is however untested support for many platforms, and you may have better luck than me.
+- Set As Wallpaper may not work on your system. It works for me on Windows 10, and macOS 10.14, but on Ubuntu 22, the wallpaper setting is updated but the picture is not, unless I manually pick it. There is also untested support for many other platforms.
 - ANSI files (.ans) are treated as UTF-8 when saving and loading, rather than CP437 or Windows-1252 or any other encodings. Unicode is nice and modern terminals support it, but it's not the standard for ANSI files. There isn't really a standard for ANSI files.
 - ANSI files are loaded with a white background. This may make sense as a default for text files, but ANSI files either draw a background or assume a black background, being designed for terminals.
 - Hitting Enter in View Bitmap mode exits the mode but may also trigger a menu item. Menu items ought to be disabled when hidden, and View Bitmap should prevent the key event from taking other actions if possible.
