@vinylizor I absolutely agree with you.
There is no reason, why a trashed audio file cannot be dragged into the project.
On every mixing session it happens at least 1-2 times, I have to look for single files in the pool to drag them back into the project.
Mostly because I am searching for additional vocal tracks to double the main vocals. Right now I have to reimport them manually, instead of using the built in pool.
There is absolutely no point in restricting that operation.
