I was a user (paid contribution) of the free PTH apps that You Control replaced so I only had to pay $9.95 to upgrade to this one. I probably would not pay $69.95 because I only use 6 of the modules. I would pay for the modules I use though. Maybe a $/module pricing plan would be more equitable and/or enticing. And obviously some of the modules are worth more than others. That said, I am very happy with You Control. All modules work flawlessly on 10.3.4. It's a great time saver for me. I don't understand why people are having trouble getting it to work. The user interface/control panel is kind of confusing at first but it's not a steep learning curve. I especially like the pop-up calendar, clip board, iCal/Address Book module, and the RSS module.
