Well, I've developed a few mods for testing new features in the engine (back when they were new anyway).
Since these mods have nothing in common, and are rather smallish, I don't want to clutter up the forums with lots of topics. I'll be posting more here as I push them to my repo (and I find where I left them :P).

bookexThis overrides the default book. When used, you can write something in it. Useful for taking notes and such.
testclockThis was to test the new Lua HUD system. It adds a clock that shows the time of the day (in-game).
crosshair_exAdds a new crosshair to the game. It does not replace the old crosshair, just overlays a new one.
hud_changeShows how to show/hide built-in HUD items.
noticeSend notices very visibly :) (sends a PM but instead of printing to chat, shows in a formspec; useful when the user isn't paying attention to you).
To uninstall a mod, just remove it from the pack :)
