Feature Request: user Flair in macro setup

[Runisco]

As someone who moderators a couple of subs where verification is needed, it would be awesome if it is possible to add a flair change to a removal macro. So that a removal macro could also change the flair text/class of a user

Also would like to be able to change flair easily, since we have a novice/intermediate/advanced flair for users, and moving users up on skill sets would come in handy.

Not a solution, but note that the mod button has an integrated flair editor which can be used for this (albeit adding another step to the process).

Related to #811 (which is the same, but for link flairs). Both this issue and the referenced one would require some fairly significant changes to the UI of the module.
