First off, thanks for adding this feature in the first place a few days ago - another addon I use used to have this feature as well, but unfortunately it broke with the DF pre-patch and hasn't been fixed/readded. So thanks for adding it!

My request is about this prompt in particular:

Having an option to skip that prompt entirely and immediately sign-up to the group when clicking on the group would be fantastic.

Added a new option in version 3.3.3 to skip the dialog :)

You're the best! Thanks!
