First of all: I think ClickUp is the most complete, versatile and promissing PM-solution available. For me, that is. Because when I introduced ClickUp to my colleagues they where enthousiastic in the beginning, but in the end they were so overwhelmed by all the possibilities that in the end they stopped using it or didn't start at all. The learning is just to steep for them.
So my suggestion is to implement prebuild setups or modes for different kind of users, like Novice, Advanced and Pro. Novice would have the basic feature with a clear and simple UX and therefore easier to learn. While Pro would have full access and therefore requires more experience and skills. Advanced... well, somewhere in between. :)
I think this will help onboarding the less experienced people and help ClickUp to become the most suitable PM/collaboration tool for everyone.
