The icons are available in three colors (black, gray, white) and four sizes (18, 24, 36, 48).
Installation:
Unpack the 7z archive.
Copy folder "black\Google-Material-Design-black_18x18\" to "<DIR_WITH_CUDA_TEXT>\py\cuda_config_toolbar\icons\Google-Material-Design-black_18x18\"
With all unpacked folders that have a color and size in the name, proceed similarly.
Run CudaText, press F1, type "toolbar icon set" and press Enter. Choose one of the newly installed GMD icon sets.
I've updated Google Material Design icons for CudaText.
Now, the icons are available in 41 colors and five sizes (16x16, 18x18, 20x20, 24x24, 32x32 pixels).
I've removed 36x36 and 48x48 - too large for toolbar buttons.
