The dev tools can be very useful to average users, even if they don't use them the same way that developers might.

For example, I know several non-technical users who use the built-in dev tools to remove the annoying overlays that some sites show, but that don't allow to be hidden without logging in or something dumb like that.

These users don't really know what the DOM is, but they do know that they can open the dev tools, click the node selection button, click on the overlay they want to get rid of, press the Delete key, and now they're able to use the site again.

Removing tabs would be awful for an overwhelming majority of users who use platforms that are incapable of managing dozens of windows.

And, as an (occasional) i3 user, I would not want this, because two browser windows seem to use up far more resources than one window with two tabs. Browsers are almost unusable once a certain number of tabs are open; I can only imagine how badly my computer would operate were the 100+ tabs I have open each consuming the resources required by a separate window.

Changed my mind, I agree with the window manager thing and that dev tools should be separate. However, ubiquitous dev tools are really nice when, as a developer, you're trying to figure out why a page doesn't work for that one user that has 20 extensions and 5 viruses and you don't have to ask them to install anything extra.

It was an extreme example to convey a point but now I realize I didn't take it far enough. My original point was that path keeping should be handle by a standalone program for several reasons: web pages aren't the only source of paths I want to keep; my primary browser isn't the only program I want to open paths in; there is often more data I want to associate with a path like a tags, notes, user names/passwords (often more than 1 pair), etc. We already have window managers so tabs are taken care of. URLs are just like file paths... Actually, my file manager looks exactly like my browser, I just don't have an HTML/JavaScript/CSS handler that doesn't also have it's own version of a file manager. The internet is just another file system and we already have file system browsers. You're right about dev tools, that should be separate, probably best to incorporate it into gdb. I think I'm on to something here.

I don't think he mean that, but this instead: "Give me these stuff. And also make it fast".

I haven't used built-in bookmarks for years. If I really want to bookmark something, it goes in Pocket or Pinboard.

Browser history search via the address bar is much faster than searching through bookmark folders for a particular page. Even nicer with Vimium where I can just hit "o" and search for what I want. For everything else, I just Google.
