Translation of Fenstersims in German-English

The change would be easy technically speaking and your feedback is very important to me. By the way, do you want me to help you with the website or take another freelancer. I left Cuba, Bolivia, and Peru.
We have learned that some tenses, such as Present Tense are easier and not as complex as others. Is that right? In my opinion, tenses in English are much easier than in the Spanish language.
I'm glad as well, thanks for the suggestions. I had little time last week as we had many important meetings. I beg your pardon. Let us continue later. Many greetings from Germany.
