Can you tell me what kind of plugin or what version of plugin can do fast 
forward well !
If some plugins can not do this well, do these plugins have bugs?

It seemed that totem does no support fast forward,is the reason that some 
plugins can not do fast forward well?

Thank you in advance for help !
Best regards!
