At MVP Summit this year one of the valuable things I learnt (which I can share ) was from Colin Dembovsky (ALM MVP) which was Using Chrome to Solve Identity Hell. Now I knew chrome profiles existed but never thought of using them to solve the problem of different identities, in-private mode was a way of doing things but you always lost that when closing the session so wasn't that great. Not going to talk much about that here, you can read his post to find out more.
I used to highlight a bunch of text (a couple of statements) then press F5 to execute that statement. With this new release you are able to easily execute the current statement by pressing Shift + F5.
