Quite some time ago i used Discord action bars and it had this nice feature intergrated. It made all spells begin cast when clicking down the button instead of when acctually releasing the button. The maker of DAB quit the Discord project some time before BC and up untill quite recently there havent been any working versions of DAB. This new, unofficial, version of DAB does not have this feature.

This would ease up some of the heavy spamming and could potentialy increase the DPS. The stopcast macros isn't realy an option for me.

So, what i'd like to know is if there is any addons for this nowdays, or if it's completly removed.

According to a discussion on the official UI boards, this is no longer possible due to the 2.0 changes, as the relevant code is now in the secure templates.

Could a secure bar make use of it? (ie, does the API still support it)
