+## Removing Inset Panels
+
+As of v4.1 (or in v3), the top and bottom inset panels both insert into the frame, inside the frame "lip", meaning that
+when everything is put together, they create a flush surface (more or less). This can make them hard to get out, as you
+can't grab anything to get any leverage, and especially with v4.1, the plastic posts to aid the friction fit make it
+even harder to muscle out --- in fact, even if you could get an edge and start yanking, you'd probably just break some
+of the plastic.
+
+You can instead use the reverse side and the hex standoffs to push a panel out, as so:
+
+1. Loosen, or completely remove, the hex bolts for the panel you would like to remove.
+2. Flip the stick over, and remove the hex bolts on the opposite side.
+3. Screw in longer bolts, or anything else that'll fit into the hole without going flush against the panel.
+4. Push the long bolts in, thus pushing the standoffs, thus pushing the desired panel out from within.
+5. You may have to even get a mallet and tap on a bolt, occasionally, as everything can be *pretty* tight.
