Hi!
I'll check what's going on in the forums with recovery email, lately it has been giving some troubles.
For the "world scaling" suggestion I guess you're already using "world mode" introduced in release 2.9, right? In theory it should be possible to add this feature to "world mode", but I guess there may be some tricky edge cases when trying to make all elements correctly aligned. But let me check it when I come back, it's an interesting feature to have!
Have a nice holiday time you too!
