I have not found this point in the Community forum, although I think that it must have been mentioned already:
EndNote-20 (I am on macOS) displays only few entries with large distance between the lines.
EndNote-X9 (and earlier) was *much* better in that.
Either go back to the line spacing of former versions, or offer control not only over Font size but also over line spacing!
(I agree with what has been mentioned a lot in the forum: the new version has not taken user needs into account!)
