Sometimes when I believe that the translator does a well job I usually do accept all.
Problem comes where sometimes I have first machine translation then user translation or mix of them, and sometimes I accept wrong formatted string from a machine translation.
My idea is to have a order in that, first show one which translator does, then machine translation.
I hope I am clear with what I mean 
Can you please specify what you mean by machine translations? Do you mean our ShareTM or something else?
Because human translations should be prioritized over ShareTM already.
Yes, I meant ShareTM, for example I got a partial Bulgarian translation, first was human, few then was from ShareTM, then again.
I will have a look at it, but it should already offer human translations before ShareTM. Maybe, some issue with sorting or other conditions.
Let me know if I am able to get log over the console or something that you need.
Thanks, but I will need to create some tests for it, so it’s replicable ;-).
