Only missing multi-desktop support

I was really excited about this app, and it looks really good too, but Im uninstalling it until it support multi-desktops : as it is its unusable for me, too much visual noise when I switch from one desktop space to another, which is all the time…
Id be really happy if we could set the image to all desktops, inc. during programmed update (hourly, etc.). Thanks in advance!
