Quick updates on the things i wanted to test:

Using the ftl-setup for /cast...

No problems at all, as expected, cause it works for follow and assist.

Using the ftl-setup with /click...

Also, no problems (as expected cause its more a wow matter,than the matter of hotkeys, but you never know...).
Works perfectly and is a big help in cutting macro configuration time in half

ToDo:
- test modifiers (and perhaps redifie my standard modifier order)
- test mouse broadcasting (low priority, as it has nothing to do with ftl)
