Raid window changes
 

As I'm sure we all see by now, previous raid windows are no longer working.

Prior to gu51 I was using a very compact raid window that I quite enjoyed.

What exactly changed in the raid window to make all the previous windows obsolete? How easy would it be to make an older raid window compatible?

The code was changed considerably to make way for the effects data (arcane, trauma, etc.) among other things.

It is not a task for the faint of heart. You should be able to find compact modes in most of the custom UI's on this site. They are sometimes called out as alternate files in the distribution zip file.

Fetish is my UI of choice and has an extremely compact Raid window by default.

Profit also has features to turn off group separation bars and so on to make the window more compact.
