Add check-in homepage widget, or menu button to CRM?

Instead of loading the Zoho People app to check-in,  Id love for my associates (who spend 90% in the CRM) to simply check-in/out from the CRM.

Will this ever be added as a feature?
Is there an extension that already does this, or currently a WIP?
Can this be created in a custom function for a menu button?

Thanks in advance...
