Grid on the side of buildings + other

Hey all

I got some suggestions/bugs that come to mind.

1) I'm not that great in getting windows/other deco on a straight line when i don't have atleast some fixation points to look at. Some kind of grid on the vertical sides of the building would greatly help to get decorations on the exact right spot.

2) When placing pillars like "Stucco pillar 1 through 4" they dont even appear on the horizontal grid of the subject you are building around.

3) The curved or octagonal column always jumps up one level when I'm building a base for a tower on 4 adjacent blocks on the grid. This way I always have to pull the adjacent column down again, which takes a lot of time in comparison to how it should be.

If this is not the right thread for bugs please tell me.
