You can though...There's some stuff in this game that seems clunky when it shouldn't be unless I'm missing something. Like if I have a playset on the base I can't go into a standard toy box from the hub. And I can't access the community stuff from the hub and the menus for them aren't great.
Pretty much everything should be accessible from the hub. It's a fun place and it's lame have to go out into the main menu for certain things.
-If you want to go to the playset, go to the center/base were the ray of light is. You enter and will be asked if you want to go to the playset, continue in the hub or quit to the main menu.
-To access community content, you go to the theater. You can individually choose Toy Boxes to download by checking the movie posters, or browse everything by talking to the host.
-To play multiplayer, you visit Flynn's Arcade.
The only one I'm not sure is to the area to create Toy Boxes in the hub or if there's any. Know that 1.0 had one for sure.
