We just upgraded our Ignite to version 8 and it is nice. First you will notice some nice useful widgets at the top of the home page that give you a good overview of what is currently going on. I like these but if you do not they give you the ability to hide them.
The other big thing that I noticed and LOVE, is the graphical plans and I can download the plan XML and use that in another tool if I want to. This makes it so easy to look at a plan and see what a query is really doing and what the costs are. It also gives you index recommendations, I am sure these are based on the missing index dmv so take them with a grain of salt, but still very nice.
Go check it out.
