well I gave Trinity Bars a spin and it's great :)
It took a long time to layout my buttons the way I like but the flexibility is great. The interaction with the bars is a bit clumsy during configuration if you ask me though. And if you spend too long configuring stuff (changing number of buttons/bars, button style, horizontal/vertical spacing) it eats up all of WoW's allocated memory for Add-Ons. It caused my WoW to crash saying that my addons were using more than 45MB of memory, please close some blah blah blah.
No biggy, just kinda annoying.
Now, my real question though is about Arcanum >.< grrr
It defaulted some of the functions to my mouse's middle button (my mouse does NOT have a middle button) and for the life of me, I couldn't find anywhere in the menu to reconfigure. In the end, I just gave up.
If anyone knows how to change it, please post a reply. thanks :D
