Make bookmark tree collapsable
Creating mobile Vivaldi bookmarks is currently a real a pain in the ass with the bookmark folder tree fully expanded and no option to collapse it. It forces users to scroll through pages of bookmark folders and it negatively affects one of Vivaldi's core features (bookmarks) and thus MANY users.
Please make the bookmark folder tree collapsed by default on Vivaldi mobile (as is the case with Vivaldi Desktop) and add options to expand and collapse again.
Furthermore, in Android (e.g. on a smartphone), you are not able to drag the scrollbar, because it is too small and has no option to touch and hold a "slider button".
