When I first saw this mod I thought it looked too good to be true! A mod implementation of a mobile crosshair? Finally, something to tide people over when the Android crosshair PR did not get merged for 5.6!
Except... Not really, because of course a mod cannot provide such an engine feature. What it really does is provide the illusion of a crosshair, but that goes away whenever you try to e.g. break or place a node, because it will not do that at the crosshair's position (like it should) but at the finger's position as usually. It doesn't allow for free camera movement either, freezing your camera as usual.
I would call this mod bullshit (akin to smearing vaseline on your screen for free bloom shaders) but someone apparently still found it useful, so I guess I must be missing something. Still though, I'll stick to playing on a fork with the crosshair PR cherry-picked and hope it gets merged in 5.7 proper.
