Coming back from a long (and well deserved ) break, I see there's a lot of new contenders in the boxing software category. Last I played I preferred HKN over Keyclone for it's excellent ability to be configured by text (and, at least at the time, better mousebroadcasting).

Now, however, I'm told that castsequence is no more and using /click is the way to go. At the same time I see that GCP has some castsequence-like functionality and looking at the webpages for HKN/GCP/ISB I have a hard time determining what programs offer the most features.

Can anyone help me by pointing out, what programs support what features or do they all do pretty much the same?
