Legion / LOQ owners

Drop Vantage but keep Fn+Q, RGB, and dGPU controls running lean in the tray.

Anyone on Windows

Just wants plugins and general system tools - basic mode keeps it useful everywhere.

Tinkerers

The llt.exe CLI, macros, and GPL source you can actually read and fork.

Help more people find a lean alternative

If UDT keeps your laptop running lean - Fn+Q, RGB, dGPU, plugins, no Vantage bloat - a star helps more people discover it and signals the plugin model is worth building out.
