I found a solution for enabling floating touch throughout the UI for Xperia Sola.
Here is a video: http://youtu.be/nzz9h3jdB-U
1.Go to system/etc
4.If you want to disable it,use the attachment,and copy paste to same location.
5.Change permissions to rw-r-r.
I have created a flashable zip,so during booting you could turn floating on and off.
Install them through recovery.
To turn on floating touch, install floaton.zip through recovery.
To turn off floating touch, install floatoff.zip through recovery.
Warnig:Floating touch is difficult to use.Needs practice.
