You mention using a 2nd CSS file to get round the issue of Form Builder overwriting my CSS, but wouldn't that mean I'd have to create CSS rules that were given the same name as Form Builder in order for the page to pick up the styles? That's time consuming (Having to go through each style, find the the ones that were relevant to my form, because not all of them are) and then write my own rules for them.
I'm not trying to argue for arguments sake here. I believe the product would be a million times better if it didn't simply create a new version of the form each time you made a change, overwriting everything. I'm hoping this factor will be considered for future releases, it would make the extension so much better.
