Constrain proportions

It’d be useful to be able to constrain proportions of a cell for the purposes of resizing cells with background images. Having the option to fit a cell to the proportions of its background image would also be great.

We tried to implement “constrain proportions” with only CSS but so far we only succeeded with a “hacky” JavaScript-solution, and decided to not include it.

Could it be handled on the macOS side?

CSS-Generation etc. is done in JavaScript, when we have time we will look into it again
