If it helps get folks more comfortable configuring niri I'd say it's a win, but personally I'm happy with editing niri's config file directly.

Also, my dotfiles come with a custom Walker menu to find and search through niri key binds, selecting the key bind will run the action too.

With that said, if you're using my dotfiles and want to use this tool, it would be as simple as adding "nirimod-git" to the `PACKAGES_AUR_GUI_EXTRAS` variable in your config file.
