It would be extremely useful for websites installed as apps to be able to have multiple tabs open in the same window. One of the possible use cases for this (and one that I would use it for) would be browsing video game wiki's while playing the game for said wiki. Technically I can already do that with how the site apps are now, but it's much more inconvenient since I would usually open a new tab to a page that I know I will need to look at later. If this feature is implemented, it would be useful if any given site app defaulted to remember your tabs and reopen them each time you launch said app.
Hopefully I posted this in the right place; I don't want to be a bother to anyone. This is where I was led to when searching for a way to suggest features for Microsoft Edge.
