No desktop PIVX icon file.

[EricStanek]

When I download a tar ball file for a Linux distro, there is no *.png for the PIVX icon.

If I want the PIVX icon to be used for the shortcut on my desktop, I have to go to Google or the Brand Assets on PIVX.org to find an appropriate size. I suspect this process is very frustrating for most users, and they are unaware the Brand Assets exist. So, they try to find the right size and file format on Google.

To better support the PIVX brand, we should include a PIVX logo/icon file in the tar ball (And other OS downloads - assuming it is missing there too.) making it very easy for a user to create a PIVX shortcut on their desktop.
