hmm i think we all got it wrong....
2 things:
Gimphoto, has all new menu's and layerthingy's (actually same as Gimpshop i suppose)
GimPad, will make everything in 1 window.. but it wont work if youre only using the Gimp, GimPad will ONLY work if you have GimPhoto (which, apparently, has not yet everything in 1 window....)
if you dont believe me, found this on another forum:
Dykam,
GimPhoto is GIMP modification with new menu layout and packed with many plugins but the interface is just like GIMP, scattered windows all over the desktop
GimPad is application that can automatically run GimPhoto and also hosted all scattered windows to single MDI window interface, just like Photoshop. (you can run GimPhoto without GimPad, but you can't run GimPad without GimPhoto, GimPad is only a utility to improve GimPhoto user usability)
there you go.... i think we have to:
either wait for Gimp 2.6
or wait for a new Deweirdifier for windows for gimp 2.4.....
* IMPORTANT EDIT *
Deweirdifier DOES still work on gimp 2.4
though the hardest problem for me was to find a download for it ¬¬
here it is for the interested ones:
http://www.groenewoudnet.nl/software/BackgroundWindow-3.0alpha.zipor indirect:
http://www.groenewoudnet.nl/software.htmldrag the .exe and the .dll files to:
C://Program Files/Gimp-2.0/lib/gimp/plug-ins...
IMPORTANT: if you finish gimp by clicking it away on the background from the dewierdifier, it wont ask you to save it.... so just save yourself or finish the gimp INSIDE the dewierdifer instead..... *bit confusing i know

*
*EDIT2*
if you cant live with gimp the way it is, install deweirdifier, but it has its cons:
-you cant set your own size canvas, only opening images, or using templates.... (probably deweirdifier doenst work optimal with gimp 2.4)
