Hi and this is a quick thing, since I’ve just started looking at Atom (good job and hope it just gets better!).
One thing that often becomes an issue when using things like Help boxes or things similar to the Command Palette is that calling it up covers the thing you’re needing help with. So it the palette could be draggable (currently, on my 13-inch MBP, it covers a decent part of the workspace), that could help. Thanks!
