Hello Max1234-ITA, as soon as FF makes that available .. see https://bugzilla.mozilla.org/show_bug.cgi?id=1225916 (but current FF developer comments on the bug do not leave a lot of hope for something coming soon .. :-( )

As for the sort, this is to come yes, although I didn't work out a plan yet. This is discussed here https://github.com/aaFn/Bookmark-search-plus-2/issues/43

Thank you, aaFn.
===================== Update =========================
"Sort by Name" is now available in 2.0.36.
