With regards to the sequence length bar above each sequence, it would be nice to be able to just click above the step you want it to go to and have the length jump to that point. Currently you have to click and drag, which can be ok at times. Also, when you make the adjustment have the option to have that sequence start over immediately or wait till it finishes it's current run then start again with the new length. Currently when you drag the bar, that particular sequence gets out of sync with the other ones and the host system as well (not timing data but position data).
Other then that, been getting a lot of use out of it.
