Will not let you add custom tags :-( – MetaGear - metadata editor Review

This is really disingenuous for an $8 app to say you can "add tags" without mentioning that only a specific list of tags can be added. I need to add the "projection" tag, the GoPro max/fusion 360 cams all fail to add that tag to still photos exported from the GoPro iOS app, and other apps can't display them as 360 spherical without the tag "projection=equirectangular".
