A mod that tries to make it a bit less of a pain to use Minecraft's vanilla developer features.

Features :

• A creative tab containing every developer blocks in vanilla that are not normally accessible in the creative inventory
• A Structure void toggle key (F4 by default) that will allow you to see structure blocks in the world in a radius around you

This mod is 100% configurable and has a config file and a config GUI through ModMenu for that matter. As well as an entry in the Vanilla keybindings options for the Structure void toggle key.

Warning: the mod is still in Beta, and might crash your game on some occasions, generally re-launching the game should allows it to function correctly.
