The users who can not use the .blend because of the RAM needed to open the file can now right click on 'Z-Anatomy-lite.blend' (at the end of the 'Anatomy Blender' folder) and open it inside the same portable version.

The main collections -corresponding to the main systems of the body- can now be linked very easily inside this empty file clicking on the buttons with their name (see image).

This option only works for Windows for the moment but there is probably a way to use it on Mac and Linux.
