Thanks for reporting, I seem to have forgotten the grid stepping management dialog 
I will add it in the next version. For now you could consider editing the main.cfg file by hand, inside it at the bottom you'll find:
If you add the line (while the application is closed)
That stepping will be available next time you start the application.
First 3 numbers are x, y, z stepping. The later 3 are the frequencies of the helper lines (every 5th line is white instead of gray in this example).
I'm not sure what you mean with 'layered structure' unless you mean the '2D grid mode's". If so there are some things on my todo list for improving working with grid mode's (multiple (ortho) views being the most important one.), and in the (far) future there will be some sort of (limited/self learning) 'auto snap/guidance' function.
The redraw issue is most likely the result of the 'Reuse front buffer' option in the main options menu, but I don't think your issue is worth disabling this optimization. Disabling it will cause considerable higher rendering times especially when many parts (or mpd submodels) are being displayed in the part bin.
