This is not a limitation specific to Bricks, but it is a truly massive PITA to deal with across most popular builders (incl. Oxygen, and the Collaboration plugin is very buggy):
It is pretty common for a site in production to have multiple people running around in the backend, and sometimes that involves working in the Bricks editor. Bricks is a disaster when you have someone working in the editor on one page, and one or more people also in the editor on other pages.
Is it within the realm of possibility for Bricks to add the ability to not be affected by multiple users working on different pages? If so, this would be such a game changer for teams and agencies that would like multiple devs working on the same site, and for businesses that have a lot of stuff being updated day-to-day.
To be clear, I’m referring to one editor per page, but many pages/templates being worked on.
