When toggling folds with zi, any folds expanding above the current line cause the current line to disorientingly jump to a different place on the screen.
How can I keep the current line fixed in the same place while toggling folds?

You could create a mapping and use it instead of using zi. Create a mark for the current position and one for the top of the visible buffer, apply zi, move to the top, move the buffer, then move back to the original position.

Instead of zi you should use zo to open a fold and zc to close it or za to toggle the fold. These commands never make the current line jump for me.
Note that these commands have a recursive equivalent: zC, zO and zA

Sure, but sometimes I want additional context from surrounding code and just want to temporarily dismiss all folds. Going around and manually opening nearby folds with zA wouldn't cause unexpected jumps, but it would undoubtedly take a lot more keystrokes.– gandalf3Commented Apr 23, 2018 at 7:14

1@gandalf3 Oh I didn't understood your use case properly. I'm not sure you'll get a good solution:
zRandzMseems to move the current line too so you might have to write a function which will save the position, handle the folds and restore the position back.– statoxCommented Apr 23, 2018 at 7:17
