It's not caching the stylesheet. If you plan on updating it a lot you should still enable caching and e.g. increment a url parameter every time you change it (like style.css?v=3).
Thanks so much! I’ve actually been using it myself for the past 6 months or so just to see how I would like it to function, that’s where the bookmarklet came from.
I’d also like to have an iOS app to make link saving that much more seemless on mobile.
I’ve also thought about a chrome plugin that would allow you to easily save opened tabs. Having too many open tabs was originally my motivation for creating linkhorse.
Thanks for sharing it :)
