I want to know what zone I am in, or what percentage of FTP I am at on the home screen. If it was up to me, I would replace heart rate with either a percentage of FTP or Current zone (tempo, sweet spot, etc.). If you wanted to keep the heart rate people happy, you could make it a setting choice, similar to choosing if you want to show instructional text.
We have an existing feature request for this over in this thread:
At the moment, this is not something we plan to add, but if it gets enough support here on the forum, that will influence our decisions in the future.
