I've seen this one suggested before - but I would love to create a few profiles that cover cross-device or multi-device lighting in advanced mode. Right now I have to sync them manually, and while it's doable, it's a bit of work.
Another thing that I would love to see is maybe integration with Corsair Link and an increase in control of the LEDs on, say, RAM and cooler pumps (let alone light strips), so that they can react dynamically to things on the key profile, and so your keyboard can easily react to, say, a thermal threshold being exceeded.
