[Testing] -Rye-:
So, I recently found a liking in this app: https://play.google.com/store/apps/details?id=com.rootuninstaller.taskbarw8&hl=de

However, it seems that the only way it brings by itself to open the Panel is a XPosed Navbar edit (worthless, as I abolished it) and an annoying floating button.

It should be possible to invoke the expanding activity using an intent I surmise, but I haven't figured out how yet.

This is the Android manifest:

<intent-filter>
<action android:name="action.com.rootuninstaller.taskbarw8.ACTION_TOAST"/>
</intent-filter>

The "com.rootuninstaller.taskbarw8.action.TASK_BAR_EXPAND_PANEL" is what I think is the key here.

(Sadly the developer won't reply to mails...)

Any help is appreciated:
