I have several Apps for only a few users and not for general access in the whole organisation. It would be best if apps remained "Private" in the "My Apps" section and not visible to the whole organisation. This would de-clutter the Organisation apps page from all the small apps users create for their own purposes. This seems to be the case for Flow, but not PowerApps.
Effectively this would give the creator the option to make the app available to the organisation or keep it private (default) and still be able to share with other users as necessary.
