Automatic Screenshot Journal
Automatic screenshot journal is still the missing key in ManicTime for me. You should buy TimeSnapper (www.timesnapper.com) and integrate it in ManicTime to make it perfect! ;)

I'd suggest that it would probably of benefit to be able to choose to only take screenshots for certain programs (mostly remote desktop) where it is not trivial to track what was occurring when (ideally you'd be running ManicTime on the remote computer, too).
