+# WebDisplays for Minecraft 1.12.2
+This is the unfinished port of the WebDisplays mod for Minecraft 1.12.2. The text below is my "TODO" list.
+
+### Missing features
+* Redstone interface
+* Server blocks (to store some of the player's web pages)
+* Screen upgrade: "laser" mouse
+* Screen upgrade: redstone input
+* Screen upgrade: redstone output
+* Peripheral: ComputerCraft interface
+* Peripheral: OpenComputers interface
+* Read config (see "Config elements" below)
+
+### TODO
+* Achievements (minePad 2 and all that stuff)
+* GuiSetURL2 missing buttons
+* Plugin API
+* Automatically add protocol to URLs
+* Using the remote control tool too far away (with a chunk loader ofc) may trigger distance guard in SMessageScreenCtrl
+* Recipes: why do I need to craft first to have them in my crafting book?
+* French translations
+* Embedded videos sound/distance
+* minePad management: check GuiContainer.draggedStack for minePad
+
+### Config elements
+* Site blacklist
+* minePad resolution
+* Homepage
+* RPMP (Real pixels per Minecraft pixels)
+* Browser language
+* Screen load/unload distance
+* Disable ownership thief item
