It's a good idea, but when you use it in real life, it doesn't work as expected. I was hoping to use the tool as a hub for all my web apps so I wouldn't have to navigate through so many web pages, but it has turned into a plugin for Gmail. It's great, but not perfect. So, I use it to find emails and important topics, but not as a platform to use all my tools in one place as their page suggests. In my opinion, it's very limited.
