I wish there was a way to make the mouse cursor stand out more when (and only when) it's over the terminal. Maybe it's because I use a dark terminal background, I can hardly ever see the thing.
There's a system wide setting to make the cursor huge, but I don't want a huge cursor everywhere. And there's a terminal preference to make the insertion cursor different, but that's a different cursor, not the mouse cursor.
When do I want to see the mouse cursor? It's useful for things like highlighting a git hash or a few lines of text for copy/paste.
