clkinfomsg: clockinfo for displaying messages count

[kamilkrz]

Read and unread. This is proof of concept but mostly working.
Only nice to have would be handling messages that was read on phone (I believe if keep msgs is not set in android, messages read on phone trigger some kind of event for removing it from watch)

Nothing fancy

Thanks for the app! Had a few questions :)

What happens here if items[1] is being displayed?

[kamilkrz]

I need some guidance - is there a chance to have context here about current CI is being shown? I don't like idea of refreshing all CI modules but in my opinion its best place to do it here.

Sure - what we have is good, the bangle health clkinfo is similar:

BangleApps/apps/clock_info/lib.js

Lines 38 to 39 in a32d268

	function batteryUpdateHandler() { bangleItems[0].emit("redraw"); }
	function stepUpdateHandler() { bangleItems[1].emit("redraw"); }

If you wanted, you could change the show function to note down which clkinfo is visible, then msgCounter could call .emit("redraw") on that, but I think what you have is fine

I'll merge, but feel free to open another PR if you want to tweak it :)
