Visual changes

[StijnVandenbulcke]

• Proposal to change to a docked sidebar and centering the text. In the current version the entire frame is centered, which is the sidebar + text, which puts the text too much to the right.
• Decreased logo size a bit.
• Also removed cosmo theme as this has thin lettering. Standard is more readable.

I agree for the logo size and removing the cosmo style. However, I personally prefer avoiding wide text frames and I liked it is centred. That's obviously a matter of personal taste 😅 but I don't have a strong opinion, so if Lieven and you prefer it that way, I'll follow you
