I'm really missing the option of having a plugin used in multi-mono / dual mono like in pro tools. Especially for compressors this can be really handy. I'm aware of the split channel way but there's 2 problems with it:
- you have to set up attack/release/threshold/ratio twice, hard to adapt to the material, really slows down the proces of mixing.
- it costs twice the amount of cpu, as a compressor will usually still load as stereo on just the left /or right channel.
