The collections feature from Saga is great and sets it apart from other apps. I believe a couple small additions could make it even better: Add a page to a collection using the keyboard (either with a shortcut, or make it so that referencing a collection will also add the page to that collection). Ability to expand the notes in the collection list view to quickly browse multiple notes. Ability to archive a collection. Collections are great for projects, but once the project has ended it would be great to archive the collection and remove it from the collection list and sidebar view.
