@tip1 Frankly, you set the tone for the discussion with your first comment. It was not very polite and to some extent insulting to a translator who has been doing his job for many years without a single complaint. Frankly, if I had received such a comment about my translation, I would have felt disrespected too.
You, as a teacher (by the way, I am also a teacher by education), could have done more positively for the browser, because it interested you in some way, since you installed it? You could have offered to help make the browser better. As a hypothetical idea, since you showed the browser to your students - maybe it would be more interesting and useful for them to try to make their own translation? This is a real project, with real results, and not just some boring homework. Here, students will get not only an interesting task, but also real experience of adult life. This is worth a lot.
We can make this translation as a second version of Bulgarian, and users will be able to choose which one they like. And your students will be able to gain experience in how software is translated - there are a lot of pitfalls, I assure you! Trust my more than 20 years of translation experience.
We are very open to all ideas. And if we can follow the wishes of users - we always try to do so. In fact, the vast majority of functions in the browser appeared thanks to our users - at their requests.
You know, the world is becoming a better place not because someone will notice its imperfections and proudly turn away. No, the world is made better by people who are ready to change what they think is wrong or not good enough. I myself started by translating the Opera Presto browser, because I thought that I could do it better than an official translator. And many years passed before I even approached a professional level - but I still receive messages about errors and inaccuracies in the translation. So perfection is unattainable, but you should always strive for it.
I hope you can change your attitude a little towards both the Bulgarian translation and the Vivaldi browser.
Happy holidays!
