It is not related to front- or backend, but rather to creation of articles in general. The way I see it;
Suppose we've got a site with 3 languages. At this stage, you'd have to create an article in the way you described, go to Joomfish, translate, save, go to joomfish again, translate again, save, go to joomfish, translate & save. Now the article is present in all 3 languages.
It would be far easier if Joomfish would offer the option to translate when adding an article. Thus, you'd essentially have 3 input fields as described above and you could create the article in one step, instead of 4 back-and-forth steps. The problem is Joomfish appears to confuse a lot of people; some of my clients simply find the process to complicated now.
