Ink Over Apps lets you draw, markup, and annotate any app on your device!
This lets the app actually create floating windows. The app will not abuse this to spam the device. The app will only use this to create the floating windows necessary.
Used when a button is clicked in the notification to close the status bar.
Both of these are used for Per app drawing. Writing to external storage happens when the app saves your drawing to disk for later use.
Get tasks happens when you start to paint and the app checks for what app is running underneath so it knows if it should give you a new canvas or pull up a new canvas for you to draw on for this specific app.
