A few things on the handbrake: mine would not really "work" very well, always seems to be on the loose side when i want to use it. Well, I never use it on parking the bike though.
But what i miss is the possibility to "put in a gear" or as with DCT "put on brakes" when - say - i have to stop beside of a slopy road! There are situations where you want to have a look at a map or figure out navi things or have a chat or whatever.... It can be tricky to keep the bike steady even on only slight rising or falling roads. What i usually do is put my foot on the brake lever so that just ok .... but also something to get used to at the beginning.
