Hello there!
My little question is, is it possible to create a circular progress bar for the battery in %.
I’ve looked around haven’t found something usefull.
Do I have to create images for all little steps or is there a easier way for that?
Would love to hear something 
Best regards

Open the example Night_Run Remove everything but hands_night_sec.png and hands_night_sec_low.png (hover the mouse pointer over them to get the full image name) in their settings instead of sync with second change it to Sync With Conditions then select Battery %.
If I understand what you want that will show you how to do it. There are other ways to do it as well, using timeline and tags.
