Pierre-André,
How to get the menu for choosing sorting options while loading a project ?
I'm not sure which menu.
With right clic we get halo as well as with alt /clic
As Bert wrote, it is intentional. For example, take a look at the DemonCastle1 tutorial. It says "to get halo, press the right button". We would keep the behavior similar across the platforms.
Thank you for the comment!
