There have definitely been a few users mentioning the odd behavior of the Home button. We have been discussing the best way to re-work items like the Home button to match an industry standard type behavior. Right now, it will adhere to either the Leftmost Measure setting or the Current Counter Setting until you reach the end of your piece which is not ideal since you would like this button to take you back to the beginning.
All of that being said, this issue has been reported and is well on the radar of our developers as they continue to work to improve Finale. I'm afraid that there is not a time frame yet for when such an improvement would be implemented, but I do know that our developers are taking such feedback seriously. I will be sure to add this report to the ticket as well.
I am glad to see that you have found the workaround as well - though it is by no means convenient, it should help get the job done given the current limitations.
