qol-plugin-os-themes

You configure OS-wide themes and cursor behavior on Linux by launching the qol-plugin-os-themes daemon and enabling desired options like Cursor Grow in the settings. It provides a centralized mechanism for managing cursor behavior and theme wiring.

The shake-to-grow cursor feature detects rapid cursor movement and scales the pointer accordingly, providing smooth visual transitions. This helps locate the cursor quickly through dynamic scaling based on movement velocity.

This cursor manipulation tool is Linux-only and relies specifically on X11 cursor control via xfixes. It enforces a platform constraint requiring X11, as xfixes is used to apply and restore cursor images programmatically.

You control the cursor theme daemon at runtime through a provided socket interface. The daemon runs as a background service, and this socket allows you to send commands to manage the daemon lifecycle and apply settings dynamically.

GTK, Qt, and icon theming support is currently a roadmap item, meaning it is planned but not fully implemented. The current limitations restrict functionality primarily to X11 cursor manipulation and shake-to-grow effects.

The best way to manage xfixes cursor images programmatically is using a centralized daemon with a socket interface. This approach handles applying and restoring cursor images while maintaining theme coherence across the desktop.
