Language Bubble

Windows utility that displays a floating bubble near the text cursor when switching keyboard layouts, showing available input languages (similar to macOS!).

• x86_64-pc-windows-msvc (Windows x64)
• aarch64-pc-windows-msvc (Windows ARM64)

Install both targets:

rustup target add x86_64-pc-windows-msvc
rustup target add aarch64-pc-windows-msvc

Build commands
