Yeah, maybe some on-boarding explanation on this could be useful. It’s quite a central part to getting started.
Architect mode is for when you want to edit system data (reorder fields, configure views, add spaces, edit users, etc.) and User mode is when you are just interacting with the data.
I understand now. Having the distinction is actually quite useful. I did a search before I posted here, and did not find this (as architect mode does not show up for the search term “mention”. Also, the mouse-over could be more informing on what the button actually does.
