I am trying to add two functionalities to dwm (running Arch linux):

1) I have uninstalled urxvt and built the AUR package rxvt-unicode-patched in attempt to fix the gap around terminal windows. The gap still remains, so is there something else that needs to be done (arch wiki suggested that this should fix issue which apparently is due to font size)? I tried the alternative of changing "static Bool resizehints" to False in config.h, which fixed dimensions but introduced a lot of redraw anomalies.

EDIT: Fixed, had to add the False value to resizehints after installing patched urxvt.

2) Is there a patch/config change that ensures that a new window stays in the tag where it was intended to be opened. For example, if I am in tag 2 and open firefox but move to tag 1 before firefox has had a chance to open, it will now open in tag 1. Is there a way to keep it in tag 2?

Thank you in advance.
