Bases organically grow pretty wide over time. When it comes time to reign that growth in, I usually use the hidden fields tool to quickly look through my fields before further inspecting them. The search feature helps, but it’s limited to filtering by keywords, which means I only find fields that are well named.
A Use Case
A user needs to look through ton of redundant due date fields. To find them, the user needs to repeatedly scour hundreds of fields for anything of the ‘date’ field type before being able to inspect more carefully. Likewise, they’ll need to look for other field types (formulas, single line text) that can also serve up date related data.
At minimum, it’d be useful to sort the hidden fields by ‘field type,’ but I’m sure there are other ideas worth exploring as well - such as alphabetical sorting, who and when the field was created (other great ones in the comments).
