This is my idea of how sidebar and desktop could both be integrated in gnome shell as one. This is the fourth time that I wanted to send this concept... The first three times I've changed my mind so hopefully I won't regret this post afterwards :P This is my first concept description so perhaps I made it a bit too long or screwed up something badly (forgot something or entirely missed the meaning of concept)... I know that it's a bit long description and perhaps not enough pictures for all of this but this is my daily drawing limit so there is a bit more text... Hopefully my English is good enough for this...
The images are on the link below (I'm a programmer not an artist so don't role your eyes too much because of poor graphics):
