Is it possible you could post up a pinned post under releases post with your current to do list and feature requests so we know whats already been requested and whats being worked on.

Requests from me would be.
#1 KW instead of HP since thats whats used most over here.
#2 External API or at least a live data stream over something like Com port. (would make tieing in my flash/scan tune software a lot easier for self tuning feature, Would just need something like torque numbers being streamed)

And just out of interest whats your software coded in? Im going to guess .Net with how the default icon is still on some win forms.
If so have a look into ilmerge so all the dll files can be packed into 1 file so then youll only have the exe and confg file.
