If you are using Microsoft Edge Browser you better know these...

The top menu bar items can help you organize your browser better.

You of course know that you open a new tab by hitting +.

But there are other things you can do.
These pictures are self-explanatory

Well, to start with, this is the top menu bar

The extreme left is indicating that there are many tabs contained in it.

When you click that icon in the extreme left, the tabs get unfolded like shown here:

Actually there are 8 tabs I was looking at.

I could restore all of them so that I can use them by clicking Restore tabs in the above view. When I do this the menu now looks like this:

If I want what is contained in these tabs as an overview I click the icon pointing down as shown here. The down pointing icon is now pointing up.

I think this is a rather nice feature in Microsoft Edge (Microsoft Edge 40.15063.0.0). 

However, there are some things very irritating with the edge. Review this post.
