there is open all to open all of the collection entries at once.
The Edge team are planning to add the Set Aside tabs feature to this new browser. collections has never been planned to replace Set Aside tabs.
Collections are to be used for other things such as adding parts of Different web pages to a single collection and then print them out in word or other formats that are going to be added in the future.
or make a shopping list from Different web stores and put them in the Same collection.

Well I do hope they replace the set tabs aside function, I haven't seen confirmation on that just that it is listed as under review. but for whatever reason I do not have the open all option. I'm on the most recent release of Dev. thanks -Giles
