This is an enhancement suggestion. My take:
When long press button down (OK in both the GH-625XT and GB-580), you get a shortcut with essential pre-exercise menues. There should not be more than 5 choices, for a quick selection.
Alternatively, the shortcuts are set in the end of the normal config menu (so a few arrow up is sufficient).
GPS Setting (to set GPS on/off, GPS Info) - maybe two separate entries
Barometer setting (or even better, manual barometer set, regardless if Auto/Manual is set).
Intervall Training (if this is implemented in the com protocol).
