This reads like a dupe of bug 3525.

But first we need Single User Login (SUL): bug 57

This is absolutely not a duplicate of 3525. I should have just left out the part about cross-media watchlists, which was only an afterthought. That's why it was in parentheses, and not part of the first/topic paragraph.

The real bug here is simpler and much more easily fixed, I suspect: I want to be able to click in the left margin on [Portuguese] or [Spanish] when I'm in English mode and get immediately from the watchlist (or any other special page associated with my English user page) to the corresponding special page associated with another language wiki that I have an account on. That bug is not mentioned at all in 3525. I do agree that 3525 is overlapping with my parenthetical remark, and I thank you for cc'ing me on that report. I'm glad it's being separately tracked, though a solution sounds like much more work and I don't expect such a solution to come soon.

This is not my bug list, and I consider myself somewhat a guest. If you guys who are doing the work want to close this on grounds of "we don't care" or "this is below our radar" or "we don't have the resources", that's entirely fine with me. But please don't close this by saying it's a duplicate of something that it isn't. I'm somewhat apprehensively reopening it on that basis, even though I feel awkward about managing someone else's space that way. I'll not fight further reclassifications, but I wanted at least a chance to appeal the closing on this basis.

On your user page you insert the interwikis to the other sites you have an account into the userpage itself.
Where would you put the interewikis which should appear in your watchlist?
Is it ok if you just list them in your monobook.js?

Other than that, we could check the centralauth table for merged accounts to list.

Changing component to "Watchlist"

Today, a fix to this task could be applied by using Wikidata's interwiki links combined with the Compact language list, right? I wonder whether Wikidata has a special policy for Special pages.

On the other hand, I don't know where does this come from, but my watchlist in ca.wiki does contain a list of links to my watchlist in other languages -- https://ca.wikipedia.org/wiki/Especial:Llista_de_seguiment -- but I wonder whether that list is fixed or based on projects I have visited:
