Apologies if this has been covered somewhere but I couldnt find it. For some reason I can only have one persona editor window open at a time. If I try to load up a new asset, it just replaces the tab with the new asset. I know for a fact in previous engine versions I could have multiple person windows/tabs open. Is this a bug, or an option somewhere? Thank you for any help.
Using 4.17.2
Jeez, sorry, looks like I can just right click and open in new window. I guess just the default behavior used to be that if you double clicked the asset it would load in a new window…? Sorry, crisis solved, feel free to delete 
I think you can force opening a new window holding shift or control or something when opening the animation too.
There’s also a setting in your Editor Settings
