Looks great! Change the name. The Raycast people are going to (initially) ask you to anyway.

Raycast also runs on Windows now, albeit in beta.

Other Linux launchers with extensibility:

KRunner: https://userbase.kde.org/Plasma/Krunner

Albert: https://albertlauncher.github.io/

There is also rofi, wofi, fuzzl, dmenu, and even gnome search providers. No shortage of launchers on Linux, all with varying capabilities.
