Something like Opera's Flow feature but better

What is Opera Flow?

opera flow is a container/space where you can send urls, text and images to from desktop and opera touch this is really handy if you are working on a project since you need these urls, etc... for a short period of time. so you don't want to them in your bookmarks which are only handy for the long term in my opinion and can only contain urls.

it would be nice if Edge for desktop and mobile would have a feature like Opera Flow but with different containers, so if you work on different projects you can create a container for each of them when you have completed one of these projects you can just dispose the container. Done. Since mostly what you send to the container is only relevant for a few days/weeks. like an article you want to read, etc...
