I posted a blog post on my (@artectrex) personal blog going over some recent changes and improvements to PixelDroid: https://artectrex.eu/pixeldroid-and-android-media-editor/

I also talk about the Android Media Editor library which is a library aiming to provide the easiest way to add image and/or video editing to your Android app,

and some exciting future plans including a new app and a revolutionary new way of doing filters :)
