AutoUnsheath

This addon will automatically unsheath your weapons whenever at all possible, effectively making it a permanent part of your transmog and not just a combat thing.
Some weapons really benefit from being unsheathed, like Brewmaster Artifact staff or Fist weapons in general.
Also can be useful with Shadowlands back attachments, as they remove all weapons from the back.

NOTE: You need to enable the addon for your spec before it works.

Console command:
/autounsheath - enables for current spec on current character
