Apologies for this late reply; I've been hard at work. I have made and am still making progress on WaveForms Live, OpenScope and OpenLogger. I've fixed some of the chart issues that you've observed, such as the incorrect channel number and scaling units, removed the character restriction when specifying units and added the DC settings to the profile, and a few other bugs. I still need to work on the firmware side to fix some of the issues you've found.
The stuff I have added to WaveForms Live is currently available on the website and I'll keep you posted about the firmware update as well.
