Want to use only a few features
 

Great mod, many things I love... but, I'm very used to a lot of the default UI. Mainly wanting to keep the group window, raid window, casting bar and the pvp immunity. I searched through the forums a bit and found that I should just delete the pieces I don't want. When I did that, however, I brutally murdered a lot of my UI. Still trying to figure it out, any help would be appreciated.

Edit: An alternative would be for someone to tell me how to get the group window to work entirely. I.E. tell me what files are NEEDED for the group window to work. I delete a ton of things that dont seem to be related... and something breaks the group window every time.

You can delete eq2ui_mainhud_groupmembers.xml, _raid.xml, casting.xml and pvpimmunity.xml from your ProfitUI folder without issues and they will fall back to default UI files.

On the other hand you can't just pick files from ProfitUI and expect them to work - it's a complete set for a reason, files are not self sufficient but have interdependencies.
