If you are like me who's still hesitant to ROOT your phone for whatever reason, then this app will help to add more Pen Window apps without needing ROOT.
MW-PEN App Enabler is my attempt to automate the process of inserting the necessary meta-data to any apps' AndroidManifest.xml to be recognized as a pen/multi window app by Samsung's multiwindow framework right within your phone without needing a PC/laptop and having to learn to use apktool/apk manager/apk multi-tool, etc.
This app implements the manual tutorial I made a couple of months ago about how to enable apps for pen window without root. As most newbies are not quite comfortable using apktool to decompile/recompile apks, I made it a challenge to find a way to simplify the process right within the phone and this app is the result of lots of sleepless nights.

The xda version below enables pen window apps (no limit) but the one on the Play Store enables both pen and multiwindow as well as multiple instances of the same app (dependent on whether app can support multiple instances).
HOW TO USE:
1. Pick apk file from sdcard (if you have a backup of the app) or pick from installed apps (system apps not possible).
2. Click Process... (the bigger the app, the longer it takes to process).
3. If target app is installed, the enabler app will prompt you to uninstall it first. (if you have important data, please make a backup first)
4. Finally, Install the processed app.
That's it. Easy peasy.
There is no way to enable system apps or apps that are already included in the rom like Youtube, Play Store, etc. Enabled apps can not be updated. To update, you need to uninstall the target app, install the updated version and then run it through the MW-Pen App Enabler app again. Not all apps are pen window or multiwindow friendly, so please don't enable every app you have. Some apps work, some don't.
