How about a activity meter?

Loved Comodo Firewall but would like to suggest incorporating an activity meter (like in zonealarm), perhaps optional so that it can be turned off based on user preference. That would let me know if my programs are accessing the internet or there is a problem with my connection and I have to reboot the router.

Thanks.

You can add that to the wishlist if you want.
There has already been a lot of requests for that, bu tyou can do it anyway if you want. There will be one soon I think.
