Hi. Long time user, first time commenter.
I just updated from r113 to 2.50 and noticed a few changes that I'm not fond of (no offense. <3)
Borders of the cast bars are scaling directly with the bar height. This looks fine on my player cast bar which is fairly large but on the smaller bars the border is barely visible, very small and dark. The spell icon beside the cast bar no longer has a border. And the option to use the default cast bar colors is no longer available.
I hate to sound picky, but I liked to maintain the look and feel of the original cast bars but with the added features of a cast bar addon, and your Castbars addon was the only one out there that made this possible.
