Grid setting in % please? And automatic integers

Hello! In our company we have to do a lot of design resizes in various proportions. So It will be very useful to have a % setting in Grid section. So I can set grid to 5% from the left as example. Just like you do in text kerning field. This way I can do resizes way much faster.

And there will be awesome if I can fix designs with decimal numbers with integers. Now I use some plugins but I wish to have some setting like “Use integers or 2x integers” in figma menu. So, as example, when I move some object it can have 2x coordinates only. Like 2,2 or 2,4 xy.
