Hi there!
I love GoodTask but I'm puzzled about the list tab behavior on desktop:
Imagine having the GoodTask window size at "20x10" (arbitrary measures for point's sake) with the List tab hidden:
If I click on the Show/Hide lists toggle the left sidebar "grows" inside that 20x10 space. Let's say we now have a 5x10 sidebar and 15x10 view inside the 20x10 window.
When I click again the toggle the left sidebar disappear shrinking from left to right so the whole window is now 15x10 and I have to resize it to 20x10 again. That back an forth every time I try to get the sidebar in view.
I know: with narrower window size the behavior is more consistent: it grows on the side and disappear. But whit more wide windows (on desktop I use mostly the column view) it could be a little frustrating.
I know that inverting how it behave would be less handy for narrowed use cases (maybe the most frequent for other users) but maybe you can consider some advanced option letting users switch from one scenario to another based on their needs?
Just my two cents about a trivial UX matter as on a broad level the app works great and I really have nothing to complain about
