Modifying materials options missing?

I can’t seem to find out how to edit materials. In tutorials online I noticed that there are more buttons available in the Materials tab.

For me it’s just Delete Material and Import Material on the Materials > In Model tab:

On the Materials > Browse tab there are no buttons available.

Was this feature (re)moved? Thanks!

yes, the free version is for hobby projects only, and although you can use existing materials from the basic library and ones you’ll find on the 3d warehouse, you can’t edit or create them from scratch. that’s in go and above.
