Ability to add custom fields to any conversation and/or task.

This could be of different formats, similiar to the capability in e.g. Notion, ClickUp, Asana etc.

So you could add a due date, a start date, priority a text description field etc. or whatever else you wanted. You could have this all configurable via the sidebar (e.g. where the Contacts info is), but also with ability to show certain fields on main conversation view so you can see at a glance important fields like due date. If you could filter by fields (e.g. due date = today) this would be super helpful.

If you could also sort by fields, e.g. due date, priority, this would be great. And also ability to sort by custom drag and drop (like in Notion kanban view), or standard (date order).
