Piwik lets you upload custom logo in the Branding Settings.
As well as uploading the Logo, it would be very nice and brand-friendly to let Piwik users upload a custom Favicon to replace our default favicon: http://demo.piwik.org/plugins/CoreHome/images/favicon.ico

This should work although not in every browser. For example IE 10 and lower shouldn't work but there was not a favicon showing before so it is acceptable for me.
