Something which has been annoying me for a while: When displaying a larger-than-viewport image file in Tear, tapping it will cycle between 100% zoom and zoom-to-fit. Unfortunately, dragging the 100% zoom version will also register as a tap on release (i.e. despite the movement), switching it to zoom-to-fit, which, well, is sort of at odds with wanting to view it at 100% and panning around.
