Please add the feature to see Last Sync status and App Condition.

I think this makes sense, I just need to think about how to actually integrate it into the app.

Having it for each app in the list view probably won't work, we might even need a new single app view

imho it could be implemented as a 'Describe' view in k9s, but the 'D' shortcut’s already taken 😁
