Hi, Attached is a patch that causes dwm to remove a window's border when the bar is hidden, and the window is the only one visible - that is, when it is the only client on the tag, or the tag is in monocle mode. It's dependent on pertag, which I use, but it could easily be hacked to remove this dependency.
Issues: - If you move a window to another monitor, it won't get resized to fill the extra borderpx*2 columns and rows until you switch to that monitor. - If you have more than one monitor, it'll be a lot harder to tell which is focussed if borders have been removed on both. You'll have to look for solid/hollow terminal cursors etc. This is just personal preference, but is worth pointing out. I don't speak C so this patch is likely very code inefficient and ugly, and it may well have other bugs. Do let me know if you find the time to clean it up.
