Which features require the commerical version of IDEA?

I once saw somewhere it mentioned that certain features of Jmix will require the commercial version of IDEA. I can’t find that list now - can someone link it?

Commercial Idea is required to use the frontend ui. It uses JS, which is fully supported only in this version of Idea.

The same like it was with CUBA Studio, if you are using IDEA Ultimate Edition - you will get such features as JPQL code completions and highlighting, and JPA Console.

Few screenshots how it looks like - here: CUBA Studio User Guide
(not documented for Jmix Studio yet)
