Hey man . I never use code folding either, but I noticed that jps implemented code folding markers where code blocks are tab indented.
That is something I've never seen before that I can see being useful.
It may be much more usable if there was a single keyboard shortcut for only toggling code folding.
This way it wont be necessary to have folding markers in the gutter to fold code.
In addition, I think pressing enter or space when on a line that has folded code should unfold the code.
For example in the image below, if my cursor is at the red (or anywhere in the code block indicated by blue for that matter except line 15&16)
and I execute a toggle folding keyboard shortcut, the whole code block indicated by blue should fold.
Later, if I'm on the line 12 and I press enter or execute the toggle folding shortcut it should unfold the code.
Again I'm not a usability expert just some 's
Edit: it may also be that I need to adjust to the current shortcuts.
