I will repost you the same letter I wrote Olga Vasileva
"Hi. First of all excuse me if this isn't the right channel to talk to the team. I am an admin at Spanish Wikisource and have a big concern about this skin, but couldn't find anywhere else to express it. I personally love Vector 2022 and would very much like to continue using it!
My issue is that interproject (e.g. English Wikipedia to English Wikisource) links are not visible anymore! This affects profoundly to the reach of sister projects.
With the old vector, interproject links had the same salience as interlanguage links. They both were in the same column. Now, interlanguage links have their own shiny button, but interproject links are buried in the "Tools" menu (collapsable out of view).
The "Tools" menu is for editors, 1% of people that interact with the page. Interproject links are primarily for users. There is some redundant linking, though: In some Wikipedias, interproject links are down in the "Authority Control" table (a visual mess) inside the "External links" tab (collapsable out of view).
Maybe interproject links should have their own shiny button. Regards,"
