better management on the left side (for faster access)

I'd like more than reordering (1).

Currently on the left site in ZeroHello, I have my sites under "favorited sites", and all others are in "connected sites" (and this takes me time to find single ZeroNet sites).

What I'd need is: "my sites" where I put my sites in, and a collapsing/expanding for this "my sites"
(collapsing, so I could reach sites faster, without moving the mouse much).

Also, I'd like many more such collapsable entries (where I can add sites), which I can name myself.

So, the structure could be like this:

"my sites"
"favorited sites"
"todo (read in future)"
"friends"
"connected sites"
" < add new entry > "
