Speaking for myself (but loudly! ) I'd prefer a set of features found on other forms designers: ability to adjust a set of simultaneously selected controls to be the same width and/or height (for aesthetic conformity) and alignment (e.g. centred, if not same width/height) and also equally distributed (same gaps).
I appreciate this can be tricky. When I have met this before, the first or last selected control (and you need to remember which applies) keeps its size or location and the others adjust to match.
But such features give a finer and more accurate adjustment than using snap-to-grid.
