All pages have a tab and preset switcher at the bottom.

These can be hidden using the SM64 Lua Redux > Navigation Bar action.

Tab Switcher

Changes the current tab.

Preset Switcher

Changes the current preset.

Presets hold a configuration of SM64Lua Redux across restarts. There's an infinite number of presets available which can be cycled through by clicking the selector.

Right-clicking the preset switcher will show a context menu with useful options related to presets.
