I came up with an idea for the website, just a suggestion. What if the homepage or the design emulates the Budgie Desktop, with a sidebar menu like Raven, task bar with sections name and icons, etc. As Budgie is one of the flagships of the project, I thought it could be a nice idea. But I don't know how realistic this is in terms of coding and web design.
I also want to say that the current design of the website is nice and clear and very easy to navigate. This post is just an idea in case any given day The Solus Project decides to change the website design.
