For anyone who is willing/able to compile it themselves, the ui-items branch of my fork has toolbar buttons for the grid rotation stuff: https://i.imgur.com/rHDULfK.png. Once the pending pull request to fix the freeze-on-load issue is merged, I'll rebase and make one for this change (and possibly ...

Glad people like it! Would be cool if, when grid rotation is not at default, the ceiling and floor flat texture rotations would automatically rotate to follow the grid? I'm probably asking too much though, heh. =P That's a definite possibility. Doing some experimenting, it seems that surface ...

No problem. I'd be happy to make it a bit more user friendly when I get some time, possibly this evening. (In the meantime, I use the following binds: Keypad-plus to align, Keypad-period to set origin, keypad-slash to reset)

I submitted a pull request to hopefully fix this issue. It seems that the first time the grid is rendered after a map load, the grid size values aren't initialized properly and you end up with size = infinity, and it caused the rotated grid drawing algorithm to go into an infinite loop. The normal ...

Hey guys, author of the grid rotation feature here. I can seemingly confirm that it freezes if you save and reopen a map with grid settings applied. I generally set the grid rotation, draw the geometry, and then reset, so I never hit that myself. I'll take a look and make a PR as soon as I can.
