I wish for browser ui innovation.
The labyrinth of ways to interact with the temporal path between pages is a cluster. History, bookmark, tab, window,, tab groups.
There are many different reasons to have a tab, bookmark, or history entry. They dont all mean the same thing. Even something as simple as comparison shopping could have a completely different workflow of sorting and bucketing the results, including marking items as leading candidate, candidate, no, no but. Contextualizing why I am leaving something open vs closing it is information ONLY stored in my head, that would be useful to have stored elsewhere.
Think about when you use the back button vs the close tab button. What does the difference between those two concepts mean to you? When do you choose to open a new tab vs click? There is much to be explored and innovated. People have tried radical redesigns, havent seen anything stick , yet.
We had that ability in Firefox, through XUL. Then it was removed. Tree Style Tab addon doesn't work properly to this day because of this.
We had that ability in Chrome, through Chrome Apps. You could make a browser app, load pages in webviews, with the whole browser frame customizable. Then it was removed.
We had an ability to make a new innovative browser, until Google infested all the standartization committees, and increased complexity of standards on a daily basis for well over a decade. Now they monetize their effort on making Chrome by removing adblockers and enforcing their own ads, knowing full well that even keeping a fork that supports manifest v2 is infeasible for a free open-source project.
There is no way forward with the web we have right now. No innovation will happen anymore.
If you expect the browser to help you manage your various workflows beyond generic containers (tabs, tab groups), then you become tied into the browser's way of doing things. Are you sure you want that?
I'm not saying your hopes are bad, exactly. I'm interested in what such workflows might look like. Maybe there _is_ a good UX for a web shopping assistant. I have an inkling you could cobble something interesting together quite fast with an agentic browser and a note-taking webapp. But I do worry that such a app will become yet another way for its owner to surveil their users in some of the more accurate and intimate areas of their lives. Careful what you wish for, I reckon.
In the meantime, what's so hard about curating a Notepad/Notes/Obsidian/Org mode file, or Trello/Notion board to help you manage your projects?
