The "Storage Drawer Controller" quest in The Beginning tab has some inaccuracies with how the drawer controller actually functions. It states that "they connect to all drawers within 16 blocks" and that controller slaves extend this range. However - I would like to correct you on this point.

Storage Drawer Controllers actually connect to drawers it is "connected to" (via other drawers, or drawer trims) within a 12 block cubic radius (This leads to a potential 25x25x25 area to connect drawers, centered on the controller). Controller Slaves do not extend this range, but act as another access point to that controller - allowing you to push/pull from any of the drawers connected to that "network's" controller.

Apologies for the correction, but it feels best not to possibly mislead players who don't know the functionality of drawers (This has been the case for a while with Storage Drawers, and configs as well as the storage drawer's curse page didnt highlight any change to me, so apologies if these changes have been made)

Add to that description (since your pushing framed drawers) don't place your framed drawers with a better builders wand, cause then it will place empty frames instead of the framed drawers :)

Updated using your language. I'm actually kind of surprised... I've believed for years that controller slaves extend the range of the a drawer controller but some simple testing proves you right.
