Hide title for certain objects – fill title property automatically based on rule/template

I suggest to make it possible to change the Title field's visibility (or even allow removing it). I do not see a purpose in giving a title to my meetings and zettels, and I don't like the "Untitled" all over my dashboard taking up space and attention. There are ad-hoc workarounds but they are unsatisfying.

Extra mile: It would be even better if you could designate another field to display as the title in the layout. For example, it would be great if I could have the meeting's date and time field to be displayed instead of "Untitled". Just to clarify, what would be great is if it were to mirror one of the fields and update upon changes to that field, not be a hard copy that is just plain text and loses sync. (Extra extra mile: a formula that can depend on multiple fields.)
