@LaSi5002 Thank you for your first webviewer contribution!
Suggestion: I would not remove the webviewer title -- the webviewer is part of the 4C organization, but not really the same as 4C, and this should be observable in the GUI.
Also: adding the logo via its weblink seems fine to me, but would there be any advantages / disadvantages if we added it statically, i.e. from the webviewer files?

@dragos-ana I can add the Title back in tommorrow. I just thought it was not really needed and that the UI looked better without it.
I also originally tried loading the image statically in quite a few different ways (even with a flask route). My conclusion was that because we use trame_server.core.Server and not trame.app.core.server.Server static loading is not provided by default and is quite a hassel to set up. I therefore just opted for the easy solution of loading it from github.
If you know how to (easily) statically load with trame_server.core.Server let me know. Maybe i missed something obvious.

The optimal solution would be to have a 4C Webviewer logo, e.g., similar to the current 4C logo, and remove the title as you did;) Since we don't have this currently, it would make sense to still keep the title. In regards to the logo link - let's keep it as it is. And if we get a better idea on how we can add it statically, we can still change this. Thanks for the good work so far👍
