New Theme and Some More Features for my cantrol panel

Hello All, I run a seedbox Company and I have a cantrol panel made to manage their seedbox. but I don't like its theme at all what you will have to do is to make a new theme for it. and you can add few more features like restart button for deluge client and can add rapidleech feature. it would be great if you know how to limit the bandwidth per user basis. I mean bandwidth not speeds. Regards, Piyush
