Tabbed and online system

Good afternoon. I'm using your app, and it's very convenient! However, I would like to have the ability to open multiple tabs with projects, as it can be inconvenient to transfer projects between partners while playing. I have to copy my project, open my partner's project, and paste my project into it. I would like to have a tab system similar to any browser, where a new tab is added when a new project is opened. Additionally, it would be great if you could add the ability to join your friend's project and edit it together, similar to how it is implemented in docs.google. Thank you again for this great app!
