How is it annoying? It's just a little button at the bottom of the screen. I think one time after they added it, they popped a window to let me know about it, but I've never seen that window since.
If you are getting something different, please elaborate.
Hey i should have specified im using an ipad. when I access the calender on my ipad the feedback gui floats in front of the screen as I scroll up and down it doesn't stay stationary at the bottom of the page. There is enough delay before it floats to the bottom to be very distracting.
I've found a way to do it in Mozilla Firefox but I don't know if you'll can do it with your ipad.
In Firefox I use the Adblock Plus, that is an add blocker and you can customize it with your own rules so it blocks the images, scripts, etc you don't want to see. I supose there must be some similar program for the ipad but I really don't know it.
To block the feedback link, you must block this path: /connect.garmin.com/resource/garmin-js-lib/backbone/apps/FeedbackApp.js?*
