About WFF and WFS, I believe one of the very missing points is to have:
- All supported Tags by WFF (Distance KM/Miles, Compass, HR is measuring?, ecc…+ all the included as external complications by the complications suite of amoledwatchfaces)
- CONDITION not just in Opacity but also in COLORS (like HR > 100 then Red else Green)
- TOGGLE switch ON/OFF for many Elements (like Analog hands/Digital Time, complications and so on…) with the goal to let users turn ON/OFF elements in Personalization Settings.
- Canvas size (450, 480, …)
The worst part of WFS is all the sub-optimal multiplication of resources we are forced to achieve with multiple layers, at the expense of CPU unnecessary usage (aka battery usage) and MB resources in the watchface that can be achieved with Conditions in Colors other than Opacity.
