yea the web browser is local software lol
but really this feature should exist regardless of autocomplete, just to reduce user confusion, so people are aware of how this stuff works instead of trying to click the login link and then failing to login and making an angry Reddit post about it
the fact that it presents a link to solve the user's problem means that the user will click on it, and currently Lemmy only shows the login link as the solution to the problem, so of course the users will click on that and then they're lost
Rather than being a form, the local software could just detect and do it all seamlessly.
the web browser won't grant access to cross domain storage
even if it did some people have multiple accounts, or may not have logged in on the current device yet, or might be browsing incognito/inprivate, so it would still have to be a form of some kind
If you want to see smaller communities, sort by "Scaled"
If you REALLY want to browse All, try the "New Comments" sort, it's like old forums
But I rarely look at All, mostly just Subscribed or Local
