Preferences

Here you'll find a button to refresh the list of addons, and the aformentioned list.

The list has an entry for every installed addon, and an eye button that lets you toggle whether you want to see that addon in the Main Panel.

The status of items that were already there is maintained when you refresh the list.

New addons will start visible if they are enabled when you hit refresh.

Main Panel

Here you'll find three sections: Presets, Enabled Addons, and Disabled Addons.

When you save a preset, it will store which addons are enabled.

When you load a preset, it will enable those stored addons, and disable the other addons.

Only addons that are set to visible in the Preferences are affect by presets.

When you toggle an enabled addon, its preferences are saved, and it is disabled.

When you toggle a disabled addon, it is enabled, and its preferences are loaded if they were saved.

Only addons that are set to visible in the Preferences appear in the Main Panel.
