i haven't read anything about either of your questions, but i am also interested. spanning one wallpaper across the three desktops would be a nice feature. about more than three though, i can't imagine a need for them.. you can get to any of your apps with the menu button (i assume), the desktops would just be for shortcuts to what you use most. it looks like you can have 20 shortcuts (see pics in this review) on each page, making 60 total. that is quick access to a LOT of stuff... still it would be cool to expand if need be.
Not necessarily...just means noone has looked into that yet....although with a bit o gimp skill i can evenly split a picture into three equal parts and set them as backgrounds accordingly...extra steps but doable. and as for the extra "monitors"...im sure there will be a spot in the software if its not an option. there is a terminal app....wonder if the xorg.conf is editable...it is linux....proly could "hack" it to support more "monitors". only reason is there are a few social networking apps that i would want to take up their own screen (facebook/twitter).
Alright, I figured it out but there's one problem...I created an image that is 1440x854, but android makes you crop the image into a 1.125:1 ratio (equivalance of 2 screens), so unfortunately (at least as far as I have been able to find so far) my previous example is as good as it is going to get. The image will be able to span all 3 screens, but there will be some overlap between the screens since your background image will be 960x854 and not 1440x854.
As you can see below, the 1st and 3rd screens combine to make the full 960x854 image, and the main screen (2nd) just displays whatever is in the middle.
