There is one thing I miss from Ableton and this is what they call "Audio Effect Rack"
In studio one can do one effect rack (called "FX Chain" in Studio One) but if we load 2 FX chains in one track, all macros are mixed and we will have A LOT of plugins inside one rack.
In Ableton, you can regroup few plugins in a Audio Rack and have few Audio Effect Rack inside your FX Chain. It is very useful, and it is a lot better for workflow in my opinion. I would love to have this in Studio One !
I tried to schematize what I'd like with a picture
