Central Mainframe Access

Hello, I'm not very good at editing this, as I'm not familiar with the Software. If Someone could assist Me, that would be great.

There's a New Pop-Up, that comes up, and I thought that other People might be interested, as it's a new Feature... Apparently.

I'm going to upload a Picture. If Anyone could shed some light on this, like, why it's there, and if only a few People get it, or if Everybody does, I'd be very interested. Thanks.
