Hi all,
Just wanted to share this very very very small timesaver:
http://bbissett.blogspot.com/2012/10/bookmarklet-restarting-vaadin.html
If you find yourself adding ?restartApplication to your URL often, the bookmarklet in that blog will do it for you, saving precious seconds off your day. 
(I just started trying JRebel – the new remoting feature for Intellij is in beta – and can finally shorten my redeploy cycle from minutes down to seconds. After that, taking 2 seconds to type “?restartApplication” became too much!)
Cheers,
Bobby
