Thanks guys for the information.
I am already using split views.
Middle-click works a charm. The only thing is that my laptop alone doesn't seem to offer middle-click (though my mouse provides it). ** Maybe the development team could make Alt-Click do the same thing, unless Alt-click is used for something else? **
bigentry, you are right. For some reason I THOUGHT that the back arrow wasn't doing its job. Either it was a momentary problem, or I was mistaken itself. Yes, it does work. I really appreciate the tip about right-clicking to add files to a playlist! I forsee myself using it regularly.
OK, the situation is now MUCH more workable. The back-arrow helps. Things still aren't perfect however, because that back-arrow gets me back to where I want, but 'clutters' that tab a bit. It's not a serious problem, but I don't like it. But maybe there is a way around it.
Let me explain. In my tab I'm looking at playlist A. While I browse and click, playlist B is shown and playlist A is now hidden, conceptually to the LEFT of B in this tab (yes a tab actually contains a CHAIN of views, only one of which is shown at one time. There are two in the chain right now). I click again and C becomes the end of the chain and visible, with A and B to the left and hidden.
I can back-arrow through the tab, back from C to B, back from B to A. Now I can forward-arrow again -- now there is 'clutter' in this tab. I don't WANT C and B in this tab. They are just temporary artifacts of my navigation which I don't want to stay in the scene, causing clutter. I don't want this chain. How can I clean it up?
It seems to me that the ideal functionality is to remove the current 'link' so to speak, in the chain of the tab. However, the X button kills the whole tab. What if Ctrl- X-button did exactly what I said? Wouldn't this be nice and clean?
