I played quite a few hours without ever pressing the 'L' key, including creating the Basis Shelter with the Crafter's Insight bonus. The 'L' key changes the display to where you can see inside your structures and turns trees into visual stumps!
Finding anything inside my Basic Shelter was very cumbersome without being able to see anything, so I gave up and destroyed most of the shelter. Destruction is basically done one piece at a time, and I left the workbench and a few floor tiles and destroyed the rest.
I accidently discovered that when I logged out at the workbench, I would get an extra 1000 crafting bonus experience to use at server restart, even though I had destroyed the rest of the building. Bonus crafting experience is good. though I eventually destowyed that workbench to fit in a Huntsman Lodge. for a 4% leather crafting bonus, I miss the Craftsman Insight and may try to fit in another Basic Shelter to all but destroy.
