@burnout426 Yes, but there is said that before O84 all methods (except dragging) of adding a bookmark would insert at the top.
I usually use right click > add site and bookmarks were added at the bottom all the time.
I never used drag and drop, but I also checked dragging right now in 78 and bookmark is also added at the bottom.
Heart menu really adds bookmark on top in O78, but the heart menu also adds at the bottom if adding speed dial bookmark (tile). I really didn't use the heart menu to add bookmarks, I used it only to change tile's thumbnail picture.
So in my case only the heart menu added bookmarks on top (in case of speed dial at the bottom),
From my point of view if all other chromium browsers add at the bottom + in Opera dragging and 'add site' methods added at the bottom also all the time, bookmarks on top looks like a bug.
But if the list is really long, then it's logical to have new bookmarks on top and the option is really need.
*Personally, I don't have long list. When the scrolling arrow appears I create new folder. If bookmarks bar becomes full of folders, I just reorganize old folders and hide them inside some general folder (so instead of the single long list I have tree of folders).
