- use FileReader.readAsDataURL (for iOS Chromium)
- add alternative Download from Server for now until proven in Prod and fixed in iOS Firefox (no i18n)
- replace cloud icons as client-side now
Consider additional cases:
- flag got reset when deleting and adding first waypoint
- don't show empty on load, postpone to update
- don't store state when hidden because empty
Use "x | y" format instead "x (y)"
(The old format was a bit confusing, e.g. the second part of the label
could be mistaken for an "explanation" of the first part, while it
actually is an entirely separate label.)
Repeat unit for every metric.
Use plural for units.
Use "-" everywhere when a metric is not yet available instead of mixing
"-" and "0".
Properly revert to initial "-" when removing route instead of showing
"0".
Show "0" instead of "" when route length cannot be calculated yet.
Slightly change wording ("Energy per 100km").
