The first thing I like about this tool was that you could create different versions to try out before writing your own version! This would be easier if there were some options in editing or deleting words/phrases.
It's not very intuitive when creating new variations but once they are created using other tools, importing them into anyother editor makes sense (eg Microsoft Word). There isn't much competition so far from Google Adwords side, just use all possible methods available online - word-to-text translation etc., get an expert opinion then go ahead by yourself without wasting too many resources at one time!! We have been able solve our customer support queries quickly because we don’t need experts; instead people who know English language better than us translate via google translator & share those translations here only after getting approval.
