Hello!
I am trying to develop an app with multiple screen faces. I wish to implement something similar to the Bangle JS app loader, where we can scroll through a menu of options and once we click some option, it leads me to some particular app. In my case, it would lead me to some screen.

I majorly wish to implement the following things:
1)My app should have a menu as the loader does.
2)It should have an option for going back to some main screen

I fail to understand how they link the various apps in the app launcher. I went through the launcher's GIT repository [https://github.com/espruino/BangleApps/blob/master/apps/launch/app.js] but can't seem to understand how this links all the apps on the device. Could someone kindly give me a hint and nudge me in the right direction so that I can work on my app.

Thank you!

When uploading apps, the Loader creates an <appid>.info file, the launcher reads all *.info files here: https://github.com/espruino/BangleApps/blob/14f5602b88843e69a9353fb4722af1d95f343080/apps/launch/app.js#L23

Formatting Help

Don't worry about formatting, just type in the text and we'll take care of making sense of it. We will auto-convert links, and if you put asterisks around words we will make them bold.

Tips:

Create headers by underlining text with ==== or ----

To *italicise* text put one asterisk each side of the word

To **bold** text put two asterisks each side of the word

Embed images by entering:

That's the hard one: exclamation, square brackets and then the URL to the image in brackets.

* Create lists by starting lines with asterisks

1. Create numbered lists by starting lines with a number and a dot

> Quote text by starting lines with >

For syntax highlighting, surround the code block with three backticks:

```
Your code goes here
```
Just like Github, a blank line must precede a code block.

If you upload more than 5 files we will display all attachments as thumbnails.
