Thanks for link, i know that page already. This feature is the one missing for us to switch from another well-known system which have more and more performance and billing problems.
That means we can finish the development of this one : that's why i asked for a status, rather than a boring "will it be ready next week" :)

I just applied the patch (roughly) and the "edit" pen appeared in Phrequent. By the way, clicking on it lead to a 404 Not Found error page.

any news here? the implementation seemed on a good way but there was no update since July 2015

Is Arcanist saving information about files somewhere? or is it just a problem with the utf8 validator?
