Bangle.js 2 speedups

hello, i have the same problem with iconlaunch and rebble.
rebble I know it's a mess and should be fixed as suggested by @Ganblejs but,

@Gordon

The fast loading won't work if the clock doesn't have widgets

does this mean that the fastload ( Bangle.showClock() ) will never work with full screen clocks?
and if so, how does the launcher know which load to use to avoid problems?

sorry in advance if I misunderstood
