I am working on a module for Prat that lets you save the chat configuration and frame layout to your saved variables.
Doing this allows you to use those settings by default on any character you log in to.
Have a look at a quick demo: https://streamable.com/as8a6y
If you are interested in functionality like this. Please join and help exercise it and work out the bugs. (BFA or Classic)
The tracker for this on GitHub is https://github.com/sylvanaar/prat-3-0/issues/80
