Add ability to update existing feature modules via UI

I would like the ability from the "Recreate" tab of an existing feature not only to download the module but also to update it as I would with drush features-update. If I've only made changes to components already in the feature, the Drush command is more convenient, but if I want to add new components to the feature I have to add them to the .info file or download a new tarball. For those cases an option in the GUI to update the feature would be most convenient. The lack of such an option is doubtless a pain point for many people—enough, apparently, that someone made a separate module for it. But it is of such general usefulness that I think it should be in Features itself where more people would find it. Anyone who develops with Features will probably use it several times a day.
