A quick screenshot of my Amiga 1000 Workbench 1.3 :
I made it with GRABBiT ^^ (I "upscaled" twice the height to have the good form factor).
And I use Intric8's icons for the HD and Ram, and many more (WShell, AmiDock, dmouse for mouse acceleration and click-to-front, morerows for overscan the WB, etc.).
I want to say a big thank you to all members of AmigaLove.com! Every time I search something about 1.3 (softwares, tips and tricks, etc.), I found a thread here
I'll make a post with more details soon
PS : Oh, I modified the Hippo's icon to be 1.3 compatible and I made a dual state "image" for this icon
