Imagine a "favorites" list of nodes -- LS, DS, Fleet, Mod, and Cantina. All your favourites are there, in a row, just like when you search for sources of a gear piece that is found on more than one node.
Go ahead and sim 5 times on each of the nodes in the first 3 categories, and burn through your energy on the last two. Refilled energy? They're all right there to node-refresh and sim 5 times again.
It's an elegant interface, especially for newer players who benefit most from having a long list of nodes to farm while doing few node refreshes.
