JuanGea - not sure exactly what you mean.
With code I’ve written, it would be pretty easy to have every face be “quadrangulated” meaning that they get divided into as-nice-as-possible looking quads and possibly some triangles. It would also not be hard to have that happen over the whole model (though one might better provide for that by just making a “quadrangulate” modifier/tool). But it sounds like you want more: first, maybe triangles are unacceptable? Second, since you say “a given quad ‘size’” maybe you intend that something like a grid fill is used, putting more internal vertices on faces to make a grid-like structure on each face where each cell of the grid has a given size? That sounds a lot harder, getting heavily into what a remesher would do.
Momotron2000 - I will look at all the rightclickselect feedback at some point, and see what I feel I can do right now. I think my current plans address most of the feedback I’ve seen on current Booleans. See https://developer.blender.org/T67744 for the design that I am executing on. Beyond what is being addressed with my current work, some future work that will come later is likely to be making enough hooks so that “bevel after boolean” can be made to work well.
