first of all I love the app, I use it for 2 years already, it is efficient and easy.
The only thing that can save me more time is: searching not in every map but searching inside one map, for example a specific subject, because the search button now will search through all my notes. For example, if I want to search "heart" in my map full of lectures about thorax, I don't want it to search every map (because I have like 1000 notes inside all my subjects that has the word "heart" in it, I only want it to search inside the map of the specific subject.
I hope u understand this suggestion since english it's not my language.

Kind regards
