Although I've just written my review for the next episode of Visions, today I'd actually like to announce an update to the YT-Series designer.
I've added a bunch on new parts to make ships with, Cockpits, Sensors, Weapons, Mandibles and Engines. Everything except new Docking Ports really, and I've reworked the options panels, putting each into it's own little scrollable area, so they all fit on the page and you can see the changes you're making rather than making a change then scrolling back up to the image of the ship.
I've played with it and tested it quite heavily over the past day or so, but if you spot any bugs or problems, please let me know.
