Hey, since i can run the Engine without Errors now, i wanted to know, how to place icons now, or those folders ( "icon Glass Walls" ) or change the place of the existing ones, is it not yet possible? like in the video "3dea at work"

It's good to read that it runs now
Our next tasks are to make everything dynamic - spaces and global icons. Currently those are static - predefined, but soon you will be able to shuffle spaces and global icons at free will. There is a lot of work to do regarding that but I hope we will deliver it soon.

Alright, i will try the newer version soon,

if there is something you want to be tested, just send a message.

do i have to uninstall and install a newer version right now? or is it possible to just overinstall or repair to upgrade ?

Install should be enough..
Newer version has some of global icons, as you could see on the Gamescom. That's the only difference..
Tnx for testing!
