Yes, thanks, i tried already some tweaks on css, and it works..
and i successfully added DUO support too.
BUT printing for me is not working. it should open an pdf file, but it just displays 'waiting for replay' and nothing happening, but when i log out from Guac then i see a save as dialog in my browser with that PDF. looks like save as dialog opens something behind them main window? very weird...
i'm on Ubuntu workstation, tried Chrome and Firefox, the same for both. Any help welcome
