I too noticed the new plugin layout. In as much as I like the auto organization of the plugs, it is taking me more time to FIND the specific plugin I am looking to insert.
Over time, this will be less of an issue and I am sure that I enjoy the new presentation better than the old one.
One of the things I do not LIKE is that my UAD plugs are doubled up with the same name and probably represent STEREO and MONO versions of the plugs but I do not know which is which yet (the first or second one on the list). I do know that inserting a stereo plug on a MONO track sounds funky and will know when I insert the incorrect one so I hope that the order is consistent throughout the list (that is, the first one is always the stereo version or visa versa).
