Build a package can take some days and my co-workers doesn't need to see them until is ready, as workaround I'm naming them like "zz@TESTING - 7z install" to group and place them at the bottom of the list.
Would be good be able to "hide" packages in testing phases.
Added to the wish list, but not sure this will be implemented to be honest. This would also require a new user role to selectively hide or deactivate packages for specific users.
