The mod adds some features that I deemed would be helpful for users.
The mod is in the early alpha stages but I do believe it to be currently stable.
Load Tune: You can put midi files into the '.minecraft\LoadTunes' folder and play one of them when your game finishes loading. (Good if you have many mods). It comes with three tunes preloaded, that were created by me. If you want to make your own tune, why don't you have a look at Online Sequencer? (You can turn it off in the config.)
Chatlog: In the config, you can turn on and off whether you wish to log the chat your client receives. The logged chat is put in the 'ChatLogs//' folder in a plain text file with a '.log' file extension and a name containing the current date and time.(from when you logged in).
Auto Elytra Equip: Do you ever try to jump off a building to fly with your elytra but forget to engage it? Well, now you don't have to worry as you will start automatically after a delay you specify in the config. (You can turn this off!)
Quick commands GUI: Quickly do commands in-game with a GUI with some predefined commands (and more coming soon).
Extra Options: Now you can change a few more options with the in-game options GUI. Including Brightness, Render Distance, Field of View, Toggling many in-game GUI elements, and a few more options.
Long chat: Allows you to send messages quicker by allowing a chat box up to 10,000 characters in length (Please note: it splits these into separate messages and if you have an input with no spaces it will only send the first 100 characters).
