Hey,

Have you tried holding down left control key for grid snap while placing/moving an object?

It's not the solution as you explained it, but before I update it into something more sufficient it should be alright.

Hey,

I have the problem with depth perception this works only until certain point.

Sorry for late response.

Would something like a grid going over X and Z axis help on this issue?

I think it would worth a try.

Please take a look at a picture attached in the link below:

Let me know if such grid would be of help.

It looks like it would be useful in fact.

Great! I'll include it in the upcoming update.
