I've been able to mod some apps to work in multiwindow mode.

How to install:
  1. Backup your data from the app using titanium backup
  2. Uninstall the app
  3. Install the modded app
  4. Restore your app data using titanium backup

Please Note:
I'm not a dev, I only added some lines to androidmanifest.xml
These apps may not be optimized for multiscreen mode, I've just enabled it.
This is just a temporarily solution.
This only works on Jelly Bean Roms.
You can't update modifed Apps with Playstore.

Modded apps:

As I can't update this post, everytime someone post a new modifed app, use this link to have an overview of all attached apps of this thread. Unfortunately, direct links to filehosters are not included
Or look at this thread created by TheSanitarium

Apps that didn't work:

  • Chrome (Error while recompiling with apk-multi-tools, even without changes, maybe someone else can edit this one)
  • Maps (same as above)
  • Play (same as above)
    [*]Youtube (same as above)

How to modify Apps by yourself:
  1. Decompile the app with apk-multi-tools
  2. Open Androidmanifest.xml with Editor, Notepad++ or something else
  3. Search for this
    Code: 
    <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
  4. Add this line
    Code: 
    <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
		<category android:name="android.intent.category.MULTIWINDOW_LAUNCHER" />
</intent-filter>
  5. Search for this line

    Code: 
    </application>
  6. Add these lines so that it looks like this

    Code: 
    <uses-library required="false" name="com.sec.android.app.multiwindow" />
        <meta-data android:name="com.sec.android.support.multiwindow" android:value="true" />
        <meta-data android:name="com.sec.android.multiwindow.DEFAULT_SIZE_W" android:value="632.0dip" />
        <meta-data android:name="com.sec.android.multiwindow.DEFAULT_SIZE_H" android:value="598.0dip" />
        <meta-data android:name="com.sec.android.multiwindow.MINIMUM_SIZE_W" android:value="632.0dip" />
        <meta-data android:name="com.sec.android.multiwindow.MINIMUM_SIZE_H" android:value="598.0dip" />
</application>
  7. Recompile app

This is cool to get multiwindow apps working. One problem is when you decompile the APK and compile it back up, you will be signing APK with a different key than developers. This means you cannot update from Play Store because the keys will not match. You will have to remove modded APK, install update, then mod updated APK. If you are ok with having older version of APK then there isnt an issue.

Will there still be an update notifier in the playstore, or do we lose that, aswell as the ability to update?

It's good to see at least some of the apps can be modded to support multi window. This is a big step of note 10.1. I have successfully modded IMO.

Is there a way I could change the default size of the pop up window? I have tried to change the four numbers for portrait apps but still the pop up is in landscape. Not convenient enough to adjust it every time.

I'm trying to decompile some of my own apps but when I'm using apk multi tools or apk manager, whenever I hit extract (option 1) or decompile apk (option 9) the script just shuts off. Anyone knows how to get it working?

It's not only that... I played with this mod since friday and there are apps, that don't work properly after you decompile and compile them!
For e.g ezPDF f.c. after opening a PDF. The reason is not this little modification but apk-tools itself, that have some problems with signed NON-system apps. Anyway GApps should be safe because you can find a bunch of "Inverted GApps"-Packs.
Could someone else try it with ezPDF?

It should be possible to write a deamon, that registeres preselected non-multiwindow apps as multiwindow apps. But unfortunately I'm not a Dev (for now :)).

I've been playing around with this mod since today and I managed to get some apps too work! ! :) I also tried with a game "Hill Climb Racing" and it's been working like a charm!

    You must delete the original app with Titanium BK and reboot before to install it (because it's a system app)!

    Here's Gmail 4.2 (with swipe to remove), multiview-enabled. (CAUTION: When dragging to resize the left and right sides, it will swipe to remove ur message. To avoid this, drag from the top corners. When dragging the bottom it scrolls down thru email list (not a big problem)
