Hans, the visibility of the rose may vary from a home file to the other. Use Plan > Modify compass… to make it visible or not. Note that it's drawn first in the plan, so it may be hidden by furniture.

I won't put compass settings in preferences because a user may want to display the compass at a different location in each home, and the geographic location of a home will generally vary too.

I just released the version 3.0 Beta 2 with two bug fixes:
- 3D models that use fully opaque PNG textures aren't transparent internally anymore. This should fix a few cases like this one when some transparent objects are in front of each other.
- SunFlow now supports transparent textures as the following image shows. [:)]
