Great work. Your design is nice. But if I may give one critique. Please add a way for users to reach the footer, it becomes silly to reach it when you have endless scroll. Either put the links in footer somewhere else and remove the need of the footer or stop the auto load after sometime and give a button for user to load more. so that they can find the footer and know more about your website.
I am sorry for you, you have a boss who judges book by its cover. Well you can always call him after the program is started and show him how it works :) that may change his mind if he is really wanting to change it that is.
Yes I am using Krita with wacom on Linux. On linux wacom and most other tablets are just plug and play. They just work. krita is just a click away from the software center.
While we (Krita) don't have 3D support yet, but we do have perspective and other kinds of rulers (assistants) support. There are lots of other features too like wrap around mode for seamless tile creation etc.
