Hi Damir,
Nice to see you on this mailing list :)
Yes, Mondrian will be replaced by Roassal. However, this transition will work pretty much out of the box (with perhaps a couple of little problems that will be fixed separately). It is already pretty much working.
What you can already do is:
- download the latest Moose image (btw, always develop on the latest Moose image)
- right click on the background, and choose RoassalEasel
- in there you can just use Mondrian scripts and they should work
Let us know if you have further problems.
Cheers,
Doru
