davatorium/rofi ? reverse-engineered prompt

Build me a fast popup app for Linux that works as a window switcher, an application launcher, and a drop in replacement for dmenu.

I want it to show a simple searchable list where I can type to filter results, use the keyboard to move around, and hit enter to launch an app, switch to a window, connect to ssh, or open a file. It should feel snappy, be easy to theme, and support both X11 and Wayland if possible, with the app picking the right one automatically. Make it handle common desktop launchers, window switching on modern window managers, and a few built in modes that can be combined together. Please keep it configurable, with good defaults, and make sure it supports UTF 8, international keyboard input, and right to left text. If you need to check current docs or behavior, look up the latest rofi manpages and version notes online first.
