I was going to post a new feature request, but thought this thread was pretty similar.
I find the search tools pretty powerful with being able to choose a combination of tags, people, ratings, plus the AND operator. However, it would be nice to be able to save more complex searches so they can be recalled with a click or tap.
With the lack of multiple journals within Diarium, I assume many of us will use tags to separate journals (e.g work, personal, dreams etc.). I think it would be really useful to save a search, especially if it's a complicated one maybe with four different people and two tags.
These saved searches would then be an easy way to review prevalent topics in your journal.
