-Whenever you pick up more than 25 itens, all the new itens collected after then will just dissapear

-You can drop the blue tiles

-If you drag an obj on the map it will teleport to the bottom of the map as if you dropped it from your inv

I'm just listing some bugs, thanks for all the work Kid and Rick

Picking up/dropping an item should force the output to update. Also I think the item descriptions should be under mouse entered. Also, wouldn't it be easier to just output all the items into a grid?

Also a fix I found on the forums earlier. It basically saves the last place you moved your item to, in the inventory window.

mob/proc/AddItems(obj/I)
    for(var/Grid/G in src.client.screen)
        if(G.used) continue
        if(!I.screen_loc) //only set if it doesn't have a screen location.
        //if picking up a new object, you'll want to set it to null
            I.screen_loc = G.screen_loc
        src.client.screen+=I
        G.used =1
        return

Also add this to MouseDrop(), if it's not there you can drag items on the map because of the default.map1 control.

        if(istype(src, /Grid/))
            return
        if(!(src in usr.contents)) return

Made a few modifications to add some extra features. Like last position of the inventory window, drag and drop from inventory window and a fix for src.client.screen = null. (the last one is thanks to kaiochao)

Wow never notice the comments on my libs. Thank you! Next time I update this demo I'll be sure to add these fixes.
