I have a place with a hundreds of folders. I go there, do a filter and get listed few folders I currently need.
So far so good.
I double click on one of the folders, do what I need to do, I go back.
Filter is not active any more! So, to proceed with another folder, I need to reenter filter setting. Not only this is inconvenient, I believe this is not what back command should logically do (it should return you to the point you were and in this case, that doesn't happen).
P.S. I would be ok with another GO BACK command parameter that would specify the filter should be restored.
