I want to suggest the probuilder developers to take inspiration from source 2's hammer editor in terms of features, because that is the best level design tools that exists right now and if Unity could have that built into their own engine, it would mean a lot of success for unity in regards to getting more people to use the engine. Because currently in this discord server I have seen a lot of people frustrated by the lack of features in probuilder (and also some annoying bugs), forcing them to move to external modelling softwares.
Also, I think spending time changing the ui was kind of a waste of time, because you could have spent this time on new features. 😓
Do the developers agree? Also, are there any features that you are currently working on, or are currently on your roadmap, that you could share?
