I can help you to do some translation and have already done most GUI translation with Loco a similar tool as poedit. My problems concern the missing core text phrases. I need the phrases from excerpt “One thought on” “NN Comment” and “Edit”. Search dialog has the header “Search Results for: ” and none of these phrases can be found in the .pot file. Before launching a theme why don´t you just put a prefix on every phrase to check if everything can be translated. For the moment working with the PRO-version are a bit of frightening as I cannot be sure it covers all my tests. Test that your team must do pre launch.
