[Request] Click casting that uses default unit frames

[jca]

Setting up click healing/casting is actually pretty easy and I know my unit frames support it and I'm sure others do as well but I haven't checked them out lately. Each unit frame will be assigned a unit identifier (ie target, target.target, group01, group02, etc) which can be used in macros w/ the '@' specifier. Using my implementation, using '%u' in a macro will replace it with @[unit] for whatever unit frame that macro is assigned to when those macros are loaded up into the addon. I'm sure other authors do something similar.

As to the right-click functionality (for the default menu), as far as I know that isn't available but I haven't had a chance to check out the 1.8 changes so that could have changed.
