I recreated the same project multiple times, previously deleting it from disk.
Now the 'Open existing app...' is populated with inexistent projects and Typesafe Activator is adding an incremental suffix to them project-name-1, project-name-2, project-name-n.
How do I remove or delete an application from 'Open existing app...' list?
It's not implemented yet. However, you can look under ~/.activator/<version>/config.json and directly remove the application there. If you want to remove all the applications either delete the file or set to {"applications":[]} We haven't documented the config.json format, because we haven't locked on a stable config file there yet, hence why it's under a versioned directory.
I believe there's already a ticket for the feature: https://github.com/typesafehub/activator/issues/17
