I’m wondering if there’s a setting somewhere in the editor or project settings, that when enabled prompts you if you’re sure you want to close any tabs before they actually close.
It doesn’t happen often, but every now and then I’ll accidentally close out of all my blueprints because of a stupid misclick on my part. Not blaming Unreal at all for that, but I can’t imagine I’m the only one who’s accidentally done that before.
If there is a “hey are you sure you wanna close this?”-esque feature, I’d really appreciate knowing!
