How someone with 10k+ bookmarks is supposed to find fitting folder? YOu cannot even ctrl+f in pop out window for adding bookmarks or scroll it by holding menu with left click... Also you cannot add tags (unless you want clutter bookmark name), when you sort bookmarks A-Z it mixes folders and bookmarks unlike in chrome. There is no option to customize this. Bookmarks search field doesn't find some folders. What else? Cannot also collapse folders easily to navigate to folder above if parent folder contains 100 subfolders you have to scroll all the way to top, i am sure you could think of million other QoL changes...
Tab management:
browsers UI didn't change since 1999: https://bigthink.com/neuropsych/tab-overload/ All we get are 4 predetermined groups for tabs? There are some addons, tho they are not good for long-term storage of tabs... Also browsers should handle this by default, so you can tag them and store them and AI context search to find tabs you have saved, otherwise you will never find some info you read/worked on 2 years ago. There is so much to improve it is crazy. How it is possible we live in information age and brain has to constantly filter information, that UI is this baaaaaaaaaaaa???
Life is absurd so...
