The Addressing Sign now supports copycat-style retexturing: right-clicking with a block item reskins the whole sign (non-consumptive; the texture is edge-preserving — top/bottom bands are kept and the middle skipped, so block borders stay intact). It also gains vanilla dye coloring (all four lines follow the dye, the highlighted row stays glowing), honeycomb waxing (freezes dyeing/editing UI/glow toggling/retexturing and wrench stripping; an axe removes the wax; scroll-wheel address switching still works), and glow ink sac lighting (emits light level 8, click again to toggle off).
