so ive been toying around and i managed to enable bookmarks search and added also fuzzy search. When a user hits <space> like in alfred then a symbol '|' will be attached in the beginning and he will be able to only search in urls. However, in my current implementation the performance is really bad since i do hide/show to filter out these elements. The logic has to be changed to accommodate then of thousands of bookmarks like in my case for example. If you are interested in contributing or checking the code i will push those changes into other branches in the repo.
