Constrain & Grid

I had to combine the last two issues in one sample file;
The attached link has 1 glyph “A”

wondering if anybody can resolve the following:
1. move nodes to be adjusted to the grid.
2. move with SHIFT key pressed any selected part or the whole glyph and keep it constrained in 90 or Zero degrees.

I’m working on Glyphsapp v. 1.4.3

True, the shift key is ineffective with certain Grid/Subdivision combos. I suppose it is a bug.

did u manage to align any node to Grid ?
