One search improvement would be predefining the search context.
My search usually starts by excluding a notebook (which is a big archive) and by checking note titles first.
I always have to write "-notebook:x title:" while, in the background, the search has already started, which is slow and annoying.
This could be improved by remembering the last search query (it does, but it is easily lost when clicking somewhere else) or better by starting with a predefined search query or context. This could be a simple string in the settings (empty by default). What do you think?
