Since we can use the REST API to show custom messages, it would be great to build them as apps.
In my case I gather data via a bash script and publish it via REST post to the awtrix. Since I want to show the information from time to time I set up a cronjob. Showing the information every X minutes. But of course this will interrupt a running app instead of just enqueueing in the active apps queue.
But it would be much more convenient to import this script as an "app" like in the appstore, so that it can be handled just like any other app. It shouldn't be necessary to build such simple apps in B4J.
