Way to see what app is currently open?

I've been looking, and it doesn't seem like there's a way to check what app is currently open. That could be useful for many reasons, like a boot script doing something if a certain app is loaded and inactive, or other apps checking to see what's currently open. I would use this in an app I'm working on, which has an app that I would like to return to the clock if a trigger happens in the corresponding boot.js script, and there's currently no way for me to do that. We could achieve something similar by just tracking what gets loaded, and updates accordingly:

global.appOpen=""
// if app is loaded, update global.appOpen
let Bangle.load=function(src){
    // not the real Bangle.load function, just a demo
    global.appOpen=src;
    load(src)
}


// Apps can then use it like so:
if(global.appOpen="sleepsummarymsg.app.js"){
    // return to clock
    Bangle.load()
}

I know something like this exists to see whether an app is the clock, but I would like this to be more extensive and track all apps.

I think you'll want to use the global.__FILE__ variable: https://www.espruino.com/ReferenceBANGLEJS2#l__global___FILE__
