$20 is VERY Fair. My personal request would be Quickbooks Integration. Anything to keep from paying Intuit's extortion
subscription fees for their web based time tracking.
Thanks and keep up the GREAT work on this very useful tool, Mr. McKeown. You can count on my financial support - I tried just now to donate $20 to your development efforts, using the Paypal Site, it was giving me endless grief. I will try again later
