When making a Text Excerpt by double clicking a word and selecting “add comment” the comment box is not active. Hence you need to click on the comment box before you can make a comment. This is also the case if you double click on an already existing Text Excerpt. If you make many of those comments, it becomes very annoying.
Another thing that changes in the last update(s) is: you can now only remove a note by clicking the arrow symbol in the right top corner. In previous versions, the note also disappeared when clicking OUTSIDE the note window. This is much more convenient. Can you set that back?
