As of today, I decided to go with the current layout of the website.
Maybe, I will write a more complex theme of my own somewhere in the future or alter an existing one but time is not on my side for this now.
This website will (hopefully) become a blog-style site with topics which may vary a lot. It may be interessting for you or not.
Anyway, you can always drop a comment to let me know what you think about it.
