I do agree with Rob too, but there is a place for both apps. The fixed car-swap apps, usable offline and online, and the creation utility. I want to come up with a good way of allowing the creation of preset packs that will swap the three demo cars over (the way I'm doing it atm is a bit cumbersome). Also when LFSTweak lets you edit ~20 values (some of which may not have clear purposes), it is possible with a little time to get familiar with it. When you have a program that can edit well over 400 values, things get a little trickier. Quick and easy to use it ain't. Essentially, by releasing a preset version first, I set the standard expected of custom cars, so once the tools are released, most people won't bother releasing 5 minute jobs.
I could go down the route of only giving the editor to people I'd think were going to make good use of it, but frankly I don't fancy getting 300 PMs from different people and then have to come up with a way to decide. Whatever way I go ahead, I want to keep some degree of professionalism to it. I'll think of it more once the first static version is out. I'm sure it will keep people amused while we discuss the way forward here.
