Usability improvements and partial redesign
As mentioned, I am planning certain usability improvements, starting with navigation. It should and will be more clear and it will be a rule for a visitor to know in which section on the site he or she is at a glance easily being able to jump back and forth various parts of the site without getting lost.
As part of the navigational redesign, the header may be redesigned as well. Here is the image showing the current concept. The aim is to make it more simple looking and still cool. Putting main horizontal menu as well as the logo in the middle gives a sense of cleanness, not to mention it will feel more logical when in a particular section of the site because the menu item representing this section will then be highlighted.
Comments, ideas, welcome.
