Set custom vault name

i have so many vaults (many projects documentation folders and hugo/nextJS websites) that have the same folder title : docs and it’s not so easy to understand in which vault i am, since i have many open at the same time.

it would be really useful if we could set a custom vault title, that get rendered in the top window bar and in the open vault selector

what do you think?
it could be saved inside the .obsidian config. nothing special…

thank you!
