An attempt by me for a more readable UI. (Too much free time)
The transparent windows are useless in my opinion because this does not benefit the readability of the content. This also demands more from the computer.
You might consider associating each window with a function key so that everyone can choose what they want to see on the screen. For example, the minimap is not necessary for me.
The readability would mean an improvement for me as a spectacle wearer because most people will not wear glasses when they exercise indoors.
The font size should also be adjustable in connection with the above.
As a serious athlete, I naturally want to see all the values that matter 
Translated with Google translate so maybe there will be some Miss Takes.
