Source: Organize your ideas with Collections in Microsoft Edge
I like to use this collection very much. During a training, I can collect all the links I get centrally and store them later in Excel, Word or OneNote. When I design a new computer, I can also collect all the test reports etc. and store them centrally in my wiki. The collection should not be understood as a bookmark and if the collection becomes large, then the browser goes a bit on its knees. i still find this very helpful.
The Microsoft website is very helpful
