Efficiently Tracking and Updating configs (dotfiles) from Multiple GitHub Repositories

I'm tracking several GitHub repositories, from which I often fetch configuration files for tools like mpv and hyprland. Given that these repositories frequently receive updates, I'm seeking a more efficient process to pull the latest changes without manually inspecting each repository and merging with my custom changes. **Current Process**: 1. Subscribe to changes on these repositories. 2. Manually download the updated config files. 3. Compare old and new config files (figure out what thing i chaged in which config, which was changed by developer) 4. Resolve conflicts manually. 5. Repeat this cycle. **Repositories** (for reference, there are many more): - - - - - This problem isn't new but i can't find any reference to this. Maybe i can't phrase it correctly.Does anyone have any strategies, scripts or tools help streamline this process? I'd like to be able to easily pull updates, see differences, and manage conflicts more efficiently.
