Android field software
I wouldn't mind seeing them revamp FG for Windows-based tablets such as my Mesa 2. While it does get the job done, there seems to be somewhat of a disconnect between the virtual keyboard and the entry fields, i.e., the keyboard will often hide the field you're trying to enter data into. That said, I really do like FG.
EGStar Android app is incredible for open source data collection. I just wish it had the US projection models built in. I can't seem to get the formulas right.
