There’s a new Empty, called ‘Image’.
But you don’t have to see them in perspective if you don’t want. In the properties of the Empty (Image) you can uncheck ‘Display Perspective’, this will auto hide the image plane,
I was a big fan of BG Images, and used it a lot.
I just tried the new system the other day, and I prefer the new system. It’s easier to manipulate the images and love having it as an empty that I can import to other scenes.
I was also ‘intrigued’ by the Collections system and lack of old layers. Once I got the chance to play with it a bit I like it now. And they’ve improved it since. So this get’s my vote, realy emjoy the new collections system.
And now we have Local View (isolate select) back. Plus check out MACHIN3tools addon, and his Focus command. It’s a really handy, it’s Local View on steroids.
