Currently you have to open the shop in the same window we chat in. This is obvious of course, as it's build into the current Discord app.
It does however, come with some inefficiencies:
- Most obviously: you can't talk and browse the store at the same time. So even though games are beautifully embedded when you actually open the game your friend linked you you'll be taken out of the conversation into the store
- Browse filters are unset after switching back and forth between a server and the store, meaning that if you and your friend/significant other/dog are browsing through the store to find a game to play together you will have to manually set these filters every time.
Looking for games and sending their links in a channel/DMs will get very annoying, but mostly just way easier if the store is in a separate window.
All in all it's just better to have the store open in a new window. The only downside would probably be the extra processing power it would take and thus be harder on older/weaker systems. This shouldn't be too big of an impact however.
