Why do you need an app? There are physical booklets.

Just why do you need an app to build Lego? The physical booklets are fine.

Still using awful broken layout

Honestly didn’t think it was possible for Lego to continue making this app worse but I was mistaken, they’ve doubled down on the grid view and now even filtered sets are shown in the new style instead of. Normal list
