That just an icon for regional changed to 4, southern cross stars are made up by 4 bright stars and also a symbol of oceania continent. So i used it to make region 4 as the stars of the south.

The stars represntng that your FMTX region is now 4 instead of 1.

4 is global frequency range.

To make it work properly you need to install ProfileX from Extra-devel.

It will make the python i'm using runs at startup. I couldn't package the file into deb ball so i use ProfileX dependency instead.

Hope this answered your questions. Althernatively you can use the Custome_swappniness shell script. I prefered the icon in my status menu because it tells me that my region is now 4.
