Is it possible to make
<C-W><C-L> command to make split on the right, if it's the rightmost pane opened? Otherwise, it would behave like regular move. It's something like "conditional splitting" I would say.
I've got two panes opened, split vertically. Cursor is currently on the right pane. I press
<C-W><C-L> and I create third pane and my cursor is moved there.
If I press
<C-W><C-L> from the leftmost pane, nothing unusual happens, I just move to the already existing pane to the right.
P.S.: which are common bindings for splitting panes among Vim users?
