WordPress Multisite (MU) compatibility

As mentioned, we would like to use the plugin at a network level.
So being able to use the plugin on any of the MU site, with a dashboard at network level, where we can see/track/edit/manage/add the short urls created in any of the sites, on a single page.

Upon short url creation for a content, on one of the network sites, the plugin would have to check that the short url hasn’t been used before on another site of the network.

Eg. on site aaa.site.com we use sho.rt/a, so if we try to use sho.rt/a on site bbb.site.com a notice should say “short url already used, please make a different one”.
Otherwise we risk to use the same short url for multiple content, in different sites of the MU network.

Thank you! 🙂
