I wish it was possible to disable “Send to Main” for the Inputs (Dual, L, R). Currently the Signal is needlessly doubled when using Overbridge. You get the dry Input via the Input Channel and you get the mixed dry + wet via the Main. Imho, it would be much better if it was possible to only get the wet Signal (Chorus, Delay, Reverb) via the Main, since you already get the dry Signal from the individual Channels.
Alternatively (or maybe in addition) it would also be useful to be able to send the Input signal to the FX without turning up the Inputs Level (on the Ext-Mixer Page).
