yachting on "[Plugin: YOP Poll] Border colour and german words"

Hello YOP Team,
must say its great plugin, but after updating i must create the polls new. Some years ago it was easy to customize the border of template Blue v3, but now its not possible i think. I can choose only this template and thats it, but looks not so good with my complete other blue i use on my homepage. In my eyes its very important to customize a poll, because it looks then much better and serious. Is there a way to realise ?

Other thing is, now i am not able to change all the english words upmyself into german. Only for the vote button and thats it. But what is with View Results or Poll total votes or back to vote ?

And is it normal that Question 1 is no more shown over the question text ?

All other is working fine, have only those 3 problems. Will be nice if someone can help me.
Best regards.
