I think an additional layout option with a tab bar allowing you to select which fields are shown (with templates per task type, and adjustable ordering) would improve the overall UX. Removing visual clutter that a user doesn't need might encourage more in-depth use of custom fields, AND with custom fields being useful to AI, it's likely people will also end up with a lot of fields that are functional, but they don't want to look at them every time they open a task. I was able to create a rough version of this in a chrome extension (minus reordering fields) without too much trouble, so hopefully the ClickUp team think it's worth adding natively.
