I posted a message about this on the Delight and got the following message from Jeff Duke:

I read your posts on the forum and have to say you nailed it for me on some of them. The main changes I would love to see are for more individual control of tracks. Mute, Reverse, Octave ( I like the idea of up or down), the ability to set loop length independently, and my most desired feature: feedback control over all tracks even when not recording on them or even when they are muted.
