In plain words

Fluor is a macOS app that automatically adjusts how the Fn keys behave based on which application is currently active. Users can set different Fn key configurations for different programs, eliminating the need to manually toggle settings when switching between apps. This is useful for those who work across multiple applications with varying Fn key preferences, such as developers, gamers, and creative professionals who rely on function keys for different purposes.

    Built this for macOS because I wanted app switching to feel faster and more flexible than the default Command-Tab flow. DashPane combines app switching and launching in one flow, with: • customizable app shortcuts • fuzzy search for apps and windows • sidebar access • edge gestures • more consistent Command-Tab behavior • appearance, menu bar, and haptics settings This is the v2 update, shipped about a month after launch. A lot of the changes came from early user feedback. Site: https://www.dashpane.pro/
