Just out of curiosity, what about XRaidStatus didn't suit you? Was it just the default look? (I'm assuming so, since it can do everything that the CTRA raidstatus can do, plus a lot more.)
If you play with the options for window itself, in addition to the individual bars that you can configure, you can get it to look exactly like the CTRA version you're used to. See the attached image for a very rough example. (The left is CTRA from an old screenshot. The right is a very quick reconfiguration of XRS while I was in Alterac Valley, which is why it's so light blue. (Too much snow!)) If you spent more than the 2 minutes that I did on it, I'm sure you could come up with something that appeals to you or looks more like CTRA's version.
If that's not what didn't suit you, could you elaborate?
I had default bars in xrs some time ago. But there is a problem with acedb handles default profiles when changing those defaults (and those defaults are saved in a table). So I decided to remove all default bars and come with a clean window.
I don't like to auto select if you're going to buff a single person or a group. But you can already cast group buffs with xrs, here is how:
In the tooltips you'll see the classes (on the right side). If there are more than 2 or 3 people missing this buff, and you want to cast your group buff, then hold shift and click on a person in that group.
