I currently use Podio, in which we can reference items across folders, boards, and workspaces.
This allows me to stack up invoices, contractors, project leads, clients, and then relate them to projects in different spaces. Airtable will not let you do it, and right now I’m not seeing that Infinity will either.
I WANT to switch from Podio, because it has some real limitations. But universal linking is AWESOME and provides such functionality. So right now I don’t see being able to replicate that.
