Ideally, when I manage access to repositories and groups in my organization, I need to make sure that I don't accidentally add someone from outside of the organization. Currently, BitBucket seems to focus on allowing me to add ANYONE from anywhere on bitbucket, and doesn't help much with controlling that.
For example, when adding members to the organization, I would like to have some kind of verification of their account - seeing names, possibly picture, etc. Currently, if I did that, I only see a little dropdown for autocomplete which is supposed to be enough for me to verify that this is indeed the right user.
Similarly, when I add users to groups within my team, I would like to ALWAYS prefer users from the organization, and have some kind of warning if I add a user to a group (or a repository) from outside of the organization.
