hi,
1, german translation: the language files are (at least these days) generated once a day, so if you just added some strings to a translation, chances are you'll have to wait until next day when all the files are generated anew.
2, 'green donut': is the 'OK' button, just like the 'red cross' is the 'Cancel' button. I must have forgotten about the tooltips, I will add them in the next release. Just consider those button traffic lights - green is Go/OK, red is Stop/Cancel. Hope this helps. I'm not planning on changing the glyphs in the near future, so you're pretty much stuck with them
thanks for the feedback, I hope you enjoy the application.
regards, Majky ...
