I often work with a lot of splits, but sometimes you just want to focus on one file. This is especially true if you move from a large external display back to your laptop's internal screen. Suddenly your matrix of six 85-by-30 windows shrinks down to a collection of unusable 30-by-15 postage stamps.
So what I want is a way to temporarily maximize the current tab, and I don't want to take the one-way ticket that is
I considered making a mapping that would effectively toggle between a maximized state (
CTRL-W | and
CTRL-W _) and everything-equal state (
CTRL-W =), but that doesn't play well with special windows like NERDTree; they get squished during maximization but never get unsquished when you try to reverse the process.
I could make a heavyweight function to save and restore all window positions; I've seen examples of this going as far as saving pretty much all state using
:mks, but that feels a bit too heavy-handed for me.
Finally I end up just doing a simple
:tabe %, which allows you to pop out into a new tab temporarily (unlike
CTRL-W T which actually moves the current window out into a new tab). When you're done, just close the tab.
