Gotta agree. As much as people around here seem to like Parrot it's never outperformed MSBT for me, even when it had several extra features. Now with MSBT version 5 I don't think Parrot has anything over MSBT, and its configuration is certainly nowhere near MSBT's.
Edit: Worth mentioning, I used SCT as well. It was a very nice step up from the default piece-of-shit that is Blizzard's FCT, but it's nowhere near MSBT or even Parrot, IMO.
I went from Vanilla FCT to SCT to Parrot and when making my new UI I decided to try MSBT from your suggestion and I lub it. Thanks! It's almost perfect! The API gave me a little trouble. I think SinkLib needs to be updated since I can't route Witch Hunt through custom scroll areas in MSBT without getting errors. Plus, I couldn't figure how to use MikSBT.DisplayMessage() so that it displays in a custom scroll area [MikSBT.IterateScrollAreas() makes my head hurt]. I got around it be renaming the default scroll areas and routing all their events into other scroll areas (basically so I could have Witch Hunt in it's own scroll area and Smartbuff in it's own as well, without other spam), which is working perfect -- even though it's a weird way to do what I want.
