Great for accessibility.

All in all the block placement logic is nice and a timer saver, especially once you get used to it. The main reason for me to like the mod, is that it can be used to prevent some repetitive clicking, you see: my fingers hurt, no idea what's up with them, but sometimes I've had to right click with my ring finger to alleviate strain (and pain) when building for too long.

So that's why I'd consider QoL feature as also an accessibility one.
