Berton,
The distance is not really important, i have problems catching the bar with the double arrow. But i changed the size of the windows inside my left screen, i use bigger windows so i need less to adjust from the inside.

Ok thanks, i am using the bar has in the red rectangle you suggested to me. It's doing a fine job after all, after a few hours of work it's getting automatic but still i have to read some text in various lenght to pick the parent folder, which takes a little bit more brain power then just clicking back to parent.
But it's ok.
