Descriptions normally get translated from one language to another (especially true for properties). However, sometimes there is the case where a description of the source language changes, and the descriptions in other languages don't get updated. There is no way to signal that the descriptions are outdated, so it would be nice to have a way to make it more clear that an action should be taken to re-align them. I also think this is important for the future Glosses. It could be that the Gloss in one language changes, and it doesn't get updated in the other languages, creating potential misunderstandings.
