They did some great fan service before. In Borderlands 2, there is the NPC Michael Mamaril in Sanctuary who can randomly give out guns when talked to. That NPC is a tribute to the real Michael Mamaril, a fan that passed before Borderlands 2 was released
I don’t think logseq has fully automated synchronization, at least it didn’t when I started using it. What it does have is the option to automatically git commit changes.
