I’m not sure if it’s been suggested (couldn’t find a thread upon searching) but I think it would be a great improvement to make a separate tab/option for the customizable photos in portraits.
From my understading as of now you go to build mode>select portrait>use the custom textures to upload a picture and use it as the portrait. Although this does work, it gets a little messy when you have lots of textures for other things (objects and such) and then pictures as well. Having a separate tab focused on pictures or for paintings/portraits at least would already be very useful and keep things cleaner for players like me who like to play with family portraits and pictures a lot and also using custom textures for objects.
I also hope the changes for the CAZ my textures UI reflects onto build mode, as now the thumbnails are very very small and hard to discern.
