-1 on feedback supression for the following reasons..
1) Its a feature associated with lower quality brands and its very existence would lower the perceived quality of the product.
2) These things teach bad habits, people begin to rely on them and all of a sudden they have a mix with 30 x 64db notch filters in it, wondering why the mix sounds like pooh.
A well balanced mix through pro speakers and microphones does not feed back. The i-Live already has all the tools you need to make a monitor mix sound great… PEQ, GEQ and Gates prevent feedback in 99.9% of situations. Feedback supressors are like training wheels, I don’t want training wheels on my mixer thanks 
A feedback supressor in the hands of a pro might be used correctly, but really, a pro doesn’t need one in the first place, which means they are more likely to be mis-used and therefore tarnish the name of the board by sounding crap. My vote is that if you want a feedback supressor, buy it seperately and insert it yourself.
Fundamentally, feedback is a sign of too much gain for a system. The cause can be crap mics or crap speakers or crap acoustics but using an automated tool to overcome a fundamental acoustic flaw is never a good idea. I always recommend trying to fix whichever of the 3 things is causing the problem in the first place.
The RTA function is more than enough to enable someone without a good ear to ring out a system prior to the gig and if you can’t hear that a mix is about to feedback then you shouldn’t really be mixing monitors. The correct time to fix a feedback issue is not 0.3 seconds after it feeds back. It is 0.6 seconds before it feeds back!
Regarding the scenes comments, I personally don’t have too much of an issue with the current way it works. I find it pretty powerful and significantly more powerful than most of the systems out there. Dumbing down the functionality to make it easier to use does not appeal to me. Granted we use our systems mainly in festival situations not theatre, but in this environment the scenes work very well. Perhaps it needs a theatre mode or a simple mode. One of the issues with having such a flexible system is that in order to be of any use, the saving mechanism must also be flexible. The ability to only store individual components of a configuration is very useful.
