Sometimes I save README's from Github to read later (there are often some really helpful explanations that I really want to use as a reference for later). However, due to the nature of Git, these things can change. It's be nice if it were possible to tell Raindrop to "re-download" the permanent copy that is stored on the server so that its index is as up to date as possible for the given page.
I'd imagine this would need to be manually initiated by the user, and not a default behavior. Wouldn't want these pages to start pointing to dead links that once existed but the original poster removed for some reason.
