I do not know if this is bug or intentional but: When searching my notes (note list search) and I want to change ordering of notes (typically to change it to title, as I normally I have sorted my notes by modification date), it clears the whole search and I have to (after changing sorting) type the searching term again. It is quite annoying.
The only workaround now is to remember to change the note order before starting to search.
