Say I have opened tabs A and B. Now I find I’d like to look at B while writing in A. So I go to B and do Cmd-K Right. This will open a pane on the right and it will show B in that pane. Very good.
However, it will also duplicate the B tab – there is now one copy of it in the left hand pane (the original one) and one copy in the right hand pane (the copy created by Cmd-K Right).
But I find that nearly always I want the original copy to be deleted – I just need one copy of the tab, and it should be in the newly created pane.
And I’d like a way to move a tab from one pane to the other.
PS: I didn’t know whether I should say “tab” or “file”.
