General

Status

The menu key, build and compatibility information, restoring defaults, and ejecting.

The Status panel is where the Client tells you about itself, and where the two destructive actions live.

Show/hide key

Rebind the key that toggles the Bubbly window. It defaults to Insert and is saved with your config.

What the lines mean

Version
The Minecraft build the Client detected.
In game
Whether you are in a world rather than at the menu.
Game data
How much of the running Minecraft build the Client recognises. loaded is a fully supported build; partial means some features are inert; unsupported means no module that touches the game will work.
LMB / RMB
Live mouse state, both as Windows reports it and as the game sees it. Useful for checking whether a clicker module is doing anything.
Screen
Which kind of screen you are on, which is what the Ignore inventories and Ignore menus conditions key off.

Restore default settings

Restores every module's registered defaults after confirmation. Anti Bot and Anti Reach Display return to on, Click GUI closes and regains Right Shift, and the shared theme and column positions reset. The external window's show/hide key is preserved.

Eject Bubbly

Saves your config, undoes everything the Client changed in the running game, and unloads. See Configuration for what is written on the way out.
