Yes, your opinion could help me a lot.
My doubt is related to basic icon size.
Popular standards for toolbars are 16x16px [SMALL], 24x24 [MEDIUM] and 32x32
[LARGE].

Looking at total number of icons and icons for certain commands group the
best solution seems to be 24x24.

Is it acceptable from i/ coding (TclTk,
wxpython) ii/ general Grass layout point of view?

I think 24x24 icons are good, as they seem to be used. Better yet, make
them in SVG so we can later render them into different sizes.

I'm very much looking forward to seeing new icons. I'd ask again, however, that you please coordinate with the interface development team on this (Martin Landa and myself most active at the moment, but also Jachym Cepicky and Daniel Cavelo). As you mention, there are some size issues that mean that new icons should not just be a drop in replacement for what we have now. I did the existing ones for TclTk quite awhile back and without much guidance on how to do it. With you working on and thinking about this in a more informed way, I'd like to take this opportunity to have a more professional-looking product than we do now.

I like the the 24 x 24 size and think that the silk alternate set are too small, at least for my eyes. However, wxPython has preferred sizes that make things work smoother. I am not in a position to check at the moment, but I think that it generally expects a default of 16 x 16. You can specify other sizes, but sometimes these have caused some odd errors if I remember rightly. I'm pretty sure that the current 24 x 24 set is rescaled to 16 x 16 in the wxPython GUI. If that's the case, it seems like the result would look better if it were drawn to that size rather than relying on wxPython to rescale them.

So we should probably test some examples to see which sizes work and look best so that you can not waste your time on having to rescale down or up.
