FR: Agenda: group items by note

There may be many items in Agenda lists: status, tags, schedule etc.
Here is an example of list of items with Finished status:

I suggest to group items by note to save some space (like subdocuments are grouped).

Thats a quite good point, as content increase, items will grow, especially in DONE status, and Tags, and maybe some customized tags, will grow with time, what I’m thinking is a search bar on top of it, a group function is very handy, thanks.
