I've realized that buying 3rd party libraries can get a bit expensive, and although the value/price ratio is insane since so many of the programs are excellent, one tends to want EVERYTHING. This is different than with regular plugins, since there you can get one EQ and two or three compressors and you've pretty much exhausted your plugin color palette. Not so with Nebula. Every color is useful for one project or another.
It would be really cool if developers could have a discount price for getting ALL of their programs. e.g. "pay $500 and get ALL my programs" kind of deal.
