I hate to be _that guy_ but since it's been a year, has there been any development? I'd ❤️ to have that feature, especially for team projects, that span multiple repositories.

Yeah, this is really something my team could use as well

I'd love to be able to issue commands like these:

# Subscribes to issues in a repo in this project
/github subscribe $org/repo issues +project:"$projectID"

# Subcribes to everything in a repo in this project
/github subscribe $org/repo +project:"$projectID"

# Subscribes to all issues in an org in this project
/github subscribe $org issues +project:"$projectID"

# Subscribes to everything in this project by this org
/github subscribe $org +project:"$projectID"

Specifically, being able to support both repository level projects and organisation level projects would be important.

A long year to die hard.

Still hoping for this feature.
