i don't feel like i can directly answer some of those questions since i'm coming at this from a dev perspective and not as a typical user who has less time to tinker with things themselves, but i recommend your programs to those users when i can and i think they make the overall nebula experience better.
if you do decide to do a 2.0, i have a few suggestions. i apologize if these are already in the current version...
2 settings in the xml have come to annoy me a bit. 1st is the max allowed look-ahead. i don't get why it's set at 1.5ms, which is not really enough to do anything. i feel like it should be at least 20ms and i don't see any reason why there needs to be a 'master' limit AND a program specific limit anyway. and if each program can have it's own limit (set by devs), then why should the master limit be so low? i want my comp programs to allow 6ms but i have to tell ppl to edit that setting to make sure they can actually provide that. just seems like a needless hassle to me.
2nd is the max timed length being 10ms by default. i don't get why it's so low. is there any negative impact from just setting that max allowed setting higher? maybe there is but i don't know of any. i know with the RateCNV it can cause longer load times if it's set high, but does max timed?
anyway so that's my tiny suggestion, that you might consider having the xmls that your prog generates have higher max settings for those, to allow for the devs to actually decide what those lengths can come to per program, rather than having to contend with needlessly low master max settings. unless you know of any reason why these settings are so low in the first place..
Nebula plugin XMLs, generated by Nebula Set-ups are actually copies of the original Nebula plugin XML file (for example Nebula3 Reverb.xml). Program doesn't alter/change any Nebula params in any way. It's up to a user which XML file will be copied/used for a new setup generation.
I agree it would be nice to have an option to tune some important Nebula params before making a setup. I will have this in mind. I would be nice to have this feature in NebulaMan, as well.
Thanks for recommending my programs to Nebula users, really appreciated
