i don't even know if i should write this, but it's annoying so ig i should.
when taking a screenshot, you can click on the notification to crop it before saving. the issue is, there are restrictions put on dimensions, so you can't have very thin images (both width- and height-wise). this is often annoying while trying to crop a line of text, extra lines are getting included in the image.
so, the workaround is to make image as thin as possible, zoom in by reverse pinching (or however it's called) and then extend the width more because you can just do that, bypassing arbitrary restrictions.
don't get me wrong, i know where they were coming from (not allowing selection that you can't easily grab anymore to make it wider), but the limit is way too restrictive. fortunately i don't need to fiddle with a different application just for cropping so that's a plus...
