This is, perhaps, corner case, but seems like a simple feature to add:
I play seated, and use my right foot to operate the SoftStep. When I do this, the alphanumeric display view is blocked by my right leg and knee. To counter this, I rotate the controller 180 deg so I can see the display. The numbering of pads is not a problem for me, as I go by location rather than the numbers. And if needed, I could always put on some stickers, I suppose. And stepping on the cables isn't an issue because I am seated and accurate. Works for me.
Currently, the software only supports capital letters and numbers on the 14-segment alphanumeric display. How about supporting lower case? Then I could use 4 letters that would result in legible text when viewed upside down (see fliptext.org, for an example of how this would work). Even better, include a software function that would rotate the text for upside down viewing; then I could just type in my text normally and flip it!
