This is a renewed version of Auto Sneak & Sprint for Minecraft 1.12.2

Original features of the mod:

Toggles for Sneaking and Sprinting with Keybinds to quick swap between toggle and untoggle state
Simplistic GUI to show the toggle state as well as the sneaking/sprinting state
Intelligent reaction to sneaking/sprinting when in toggled state. Hold the button for longer (configurable duration) to not go into the toggled state.
Ability to increase creative mode flight speed when sprinting

My changes to it:

added ingame-accessible and ingame-modifiable configs
added ability to automatically unsneak when starting to sprint from toggled sneak
fix sprinting not being toggleable when flying
increased max flight speed boost
added configs to allow to move the simplistic GUI by pixel from the 9 base states
reduced alpha of blue simplistic GUI to make it less jarring

Default Controls:

G - Toggle Sneak On/Off
V - Toggle Sprint On/Off

These controls can be changed in the Minecraft control window. To toggle sneak/sprint, press the appropriate button briefly, and it will hold it down.

The source code for the mod can be found here: https://github.com/nischhelm/ToggleSneak

The original mod "Auto Sneak & Sprint" was a remake of BlauesZebra's Toggle Sneak, which was outdated, you can find it here: https://github.com/BlueAnanas/ZebrasToggleSneak

Note: if you have used the old togglesneak before, youll need to delete the old config and let it regenerate, otherwise it will crash during startup. Caught that too late, sorry!
