Being able to add FX to the Pro Channel is nice, but it really falls short in that you can't see what effects you have on your tracks/buses.
When they are in the FX Bin you can get an overall idea of what's on your tracks and get a rough idea of what load is being placed on your system.
For example ... this project has roughly 50 FX in it ...
I've been forcing myself to use FX Chains
only because I can see them phasing out the FX Bin, which I vehemently appose, but there's nothing I can do about it.
