Hello, I've written a small patch that allows dwm to swap the contents of two tags.
As this is my first time actually hacking into dwm's code I'm looking forward to receiving some feedback. Also, if more people find this useful I would like to make it publicly available in https://dwm.suckless.org/patches/ .
I sent this patch to [email protected] but I think it belongs better here. Best regards, Ricardo Jesus
