Hello!
Please make a tile selection window with a limited size, for example, so that only 10 tiles fit in one line, that is, so that the window is not long.
Or, alternatively, arrange the tiles in groups, so that in one line there are only tiles of a certain group, for example, in line 1 - asphalt, in line 2 only regular concrete, in line 3 - refined concrete.
And for some reason concrete with a hazard marking is not displayed, although they can be made in different colors (mod Dectorio).
And is it possible to add a hint with hot keys when hovering over the mod icon?

I did not include the hazard concrete for this very reason, too many to display. This request does not come as a surprise.
I will see what I can do, more gui work... yuck. :)

It would be cool if you make changes, because at the moment the window is long :)

P.S. I didn't know that working with GUI is complicated :(

I just uploaded 2.12.6, I hope it works well enough.
The sorting is less than I would like, but sometimes compromise is best.

Thank you!
