Do you want your Explorer to have the task pane on the right side like this:

Well I will show you how to do it.
I first saw this in Nano VS and I liked it so I decided to do it myself. I have done this to the Aesthetic Groove visual style by Heylove (which by the way is my favorite VS, thanks very much heylove).
Tools Needed
Resource Hacker (Right Click Save As)
Step-By-Step
1) This all envoles a file called Shellstyle.dll, included in many themes, when you download a theme if you are using a hacked ux_theme.dll you drop it in the C:\WINDOWS\Resources\Themes directory. You then have the theme folder, we will use "agroove" an example like such:

2) When in your VS' directory open the "Shell" directory. Inside ussally will be all the different style options for your theme, such as compact, full and various other choices like this:

3) Within that directory you should have a library called Shellstyle.dll drag it into the program we downloaded before called Resource Hacker.

4) When in Resource Hacker navigate to UFILE>1.

5) After you have navigated to the right script look towards the bottom of the script and you should see some code that looks similar to this:
CODE

Replace the code you found with this this code above.
Then press compile script at the top and File>Save.

Conclusion
Once you have done all this you can reload your theme, you can reboot explorer.exe or you can restart to make your changes affect. Enjoy, I have seen many people want to do this.
Tell me how it goes.
