Hash tag format support

Can we allow pinning hashtags to the side bar, so that people can click on it and see all the notes with that hash tag? Or even better, allow saving search to the sidebar (in which case the hashtag will be a special use cases since we can search by hashtag). It’s like a virtual category, but allows notes to appear in more than 1 of them.

You can do this already: Searching and Filtering
