Loving this thread! lots of info, I have been using Matan's hildon-desktop for a long time now but there is other improvements coming to light now that I also want to try but am disappointed that I am having to go back to 4 homescreens. I am now trying this

and am enjoying it. I also would love to try others but it is a shame that there is not just 1 complete "mother of all hildon-desktops" with all current working mods included such as the two I have discussed along with the faster scrolling, keyboard shortcuts etc, and by looking through a lot of threads all around the moded desktops I can see this is something that a lot of people are asking for.

Is there anyone working on such a thing at all??
