Nice cart. I like the double thick top. Makes a solid foundation for both the saw and the outriggers. Much of the time, I need extra support to the right, so my thought is some sort of extension on rods passing through a pair of channels in the base. Pull it out and you get an extension of about 2 feet, for a total of 3.5 feet of outrigger support from the blade.

Three thicknesses of base required, but top and bottom layers could be half inch and use pine boards of varying width to form the channel(s). Folded in, the outriggers only add an inch or two to the table width. The channels need to be a very close fit to whatever rods are used for the slider. Except for very long stock, this would do the trick. More convenient than a roller stand anyhow.

Come to think of it, adding a couple of T-slots on the inverted U shaped outrigger top would give you an easier way to clamp the workpiece than fiddling with a loose clamp each time. With a long enough bolt, you'd be able to handle almost any workpiece.

I was thinking about making this cart and how to make the outriggers exactly the right height. It dawned on me that you would lay the top of the outrigger on the top, then add what would become the sides, put it atop the "top" and mark the side along the edge of the saw's table. This would give you the exact height. If you used a rabbet on the top, that would still give you the exact height. Once glued, it would be very easy to mark screw locations and attach the top with precision. A brace placed inside the outrigger would keep it square and help it support weight. I know this seems obvious, but maybe not to a nubie.

@tomp913 The middle layer could be made of the same stuff as the board carrying the outrigger. Add some very thin veneer to these cross pieces so you have a tight fit that still allows the outrigger board to slide. I'd want to add a really good hardwood edge to the board for more rigidity, and I'd want that board to be fairly wide. I would keep the inverted U outriggers to stay on the top and would use a single vertical board for the extended support to keep it as light as possible. The sliding outrigger would most likely be used only for long and dimensional lumber, which can be quite heavy.

I think all this speculation means we really like this thing!
