Ability to make frames unread like comments

In big projects, where is mane frames updates quickly and need to be checked by art-director i need feature to make frames where i make changes.

For example: I have few pages (Main; Servers; Service; Support) where i place frames of this category. And yesterday i make some changes in “Servers” section in frame “[1024px] Servers → Ready servers (Inner page)”. So, instead of add comment to this frame i prefer to make FRAME unread, like comments, so my art-director can view this status in pages and then in frame

Maybe show list of this frames in comment section by tabs (Comments/Changes)

This will be so helpful in big projects!
