During November 2025, contributed to the macvim-dev/macvim repository by developing a cross-window manager configuration feature focused on i3-related config loading. This work introduced support for the 'all' option in i3's popup_during_fullscreen setting, aligning with i3 version 4.24 behavior and enhancing fullscreen popup reliability for i3 and sway users. The implementation involved resilient Vim scripting and careful configuration management, ensuring swayconfig compatibility by programmatically removing unsupported options after sourcing i3config. By addressing runtime configuration errors and reducing support overhead, this update improved the user experience for tiling window manager environments, leveraging skills in VimL, syntax highlighting, and Git-driven workflows.
