Thanks for the quick evaluation and for the kind words !
It would indeed be better but I fail to see how I could achieve such a result, if you have any idea I'm all ears. The problem I see is that while most apps use a predictable link pattern, some don't (for example Vimm.TV only requires the author's username). Besides, the allowed_apps sub-setting in the config.json file already lets users decide which app they want to see. If the value of an app is set to 0 its posts will not be shared. If it's set to 1 they will be shared with a link to the default app. If it's set to 2 they will be shared with a link to the original app. The website I announced in the "What's comming next ?" section of this post should also ease the app selection (and all other settings for that matter) for users.
