Inkscape does have less features compared to Illustrator, I just prefer it over Illustrator because it doesn't have built-in AI "art" garbage.

Just that it doesn't have stuff for special lineart properties. e.g. crayon/chalky brushes, etc. just a pencil tool, calligraphy, and that's it.

(also had to check for a bit, I didn't find any special properties.)

If it is possible, is there a plugin for that, or something?

This topic was lost in a time vortex. We reversed the vortex and brought it to the present time.

I don't think there is a way to import ai brushes, but Inkscape users are finding creative ways to make brushlike tools.
