Today's update adds something that Rolling Line has desperately needed since day one, properly organized drawers!
All the drawers have now been grouped into categories (like trains, track, buildings etc) and completely re-organized.

Simply click the category icon to set the overall category:
Then click the number to choose individual drawers, or use the arrows to cycle through all the drawers in the current category:
This new system might take some getting use to, but it SO much easier than the mess that it was before.
