Most importantly, the ability to alias the parameter's name in the Ableton "Configure" parameters container. Sometimes Ableton will pickup an inscrutable "Host Automation..." name from the plug in, or a name that's so long it's impossible to read since it's truncated both in the desktop as well as Push UI.
Long and short: aliasing is a solution (coming from Bitwig - this aspect is well managed). I'm crossing my fingers!
I realize I can utilize Ableton's macros and name them to my heart's content, but it adds a couple of steps to the workflow, and does not have a two way communications with the plug in.
Thanks for your thoughts and knowledge.
