They’re just so unintuitive on iOS. When the bookmarks shortcut is enabled in the toolbar, I’d expect to be able to tap and hold the bookmarks icon to get a popup menu to add a bookmark, as I can do with the tab manager icon. Instead, that doesn’t work, AND even going into the bookmark manager there is no way to bookmark the current tab. You have to go into the three dots menu, scroll down and then look for the button to add a bookmark.
It would also be great if we could drag and drop bookmarks to move them, or have a Select + Copy + Paste Here interface like that found in many file browsers, instead of what is currently done.
