I've been waiting for quite long time to post a review, but by now I can definitely say that this is the best WordPress plugin for working with po files.
... well, actually is the only one! ;)
The only missing thing is providing some reporting for po files, like issues, where are these issue, if a po file has multiple domains, where are these domains used, etc.
But this is just some nice feature I'd like to see: the plugin itself it's already ok as is.
... and way better than poEdit!
