When I had my TS setup in the shop, I had a 48" length of 2x6 bolted to the left side of the saw. It was originally planned to be used to assist as an outfeed help. I had it mounted on two brackets holding it about an inch and a half way from the saw table. i soon found out it was as much help as an added work surface as it was for an outfeed platform. When i found out about fedtool and got some of those little festool clamps, i found dozens more uses.
I made up all sorts of jigs as I often used the saw as an extra work bench.

I have something similar in size and location and find it extremely useful.
I started installing a Delta sliding table on the left side of my TS several years ago (pre Festool) and changed my mind partway through because the sliding table would take up too much space. I had already installed the 2x4 (inch) 5 ft long steel tube that the main tracking bar is mounted too and decided to leave that.
That long strong secure rectangular steel tube as a clamping surface has become my go to station for everything that doesn't require the MFT. I can clamp horizontal pieces to the top and vertical pieces to the face of the 2x4 tube. I am constantly sanding there. It is at a much more comfortable height than the MFT and since the TS is bolted to the concrete floor, and I installed angle iron posts to support the TS extension wing the hardware is attached to, I can practically use the thing as a leg vice.
I went to a lot of trouble to solidly install my TS level with my old European style bench (which has become a mere shelf) so I'll keep my TS even if it too devolves into a mere table.
