Interested.

This is already a thing.  https://support.atlassian.com/jira-work-management/docs/advanced-search-reference-jql-functions/#Advancedsearching-functionsreference-projectsLeadByUserprojectsLeadByUser()

This is a must have feature. If software developer collaboration tools (like slack) already support this I don't know why Jira should be behind on this

would like this too. also, it would be great if more input can be available at Project Settings too. Right now there is only Project Category. I have alot more input required at project level than just this.

Interested

The function projectsLeadByUser() it's ok,  but I need to see name leader in the resultset table from a JQL filter.   I can`t to select project flieds to configure the resultset columns. 

The same for confluence filtering for Jira issues. 

I'm using Cloud, but my problem was solved using this JQL search: project in projectsLeadByUser() AND status = Open

+1 We could absolutely utilize this on our project.  We have multiple teams, each maintaining several projects, it would be great to be able to sort results by team lead (which we set to project owner) in order to categorize the projects by the teams they are associated with without having to filter out the other teams.

+1, it is a very convenient feature.
