Oh. I'm trying to think of how I would put it into words.
Like, having a search engine on this site, where you can look things up while having the chat (or post) on the same screen, instead of opening it up in another browser. That way, you don't have to leave the tab or window to do research.
For example... I'm in the middle of doing something on E, and I realize that what I write requires more research. Instead of opening up another tab, it would open up on the same page you are working on, that way you don't have to leave the page at all, and you don't have to worry about accidentally closing out the tab that you are working on.
It's just a random idea, and I can delete it if you want me to.
