I find this plugin very useful, but I want to use its features on my Multisite installation that already has many sites... so I suggest an option to run all tweaks on all sites (or selected sites).
I know there is a plugin "sitewide options" or something but not sure if this could be done in a combo with your plugin...
Cheers!
