Hi, thank you, share it with your friends and colleagues to help Linguist become a mainstream tool for translation and replace a proprietary software who care about make money on product, not about quality and privacy.
For now Linguist no have feature to hide some languages, but recently used languages appears at top of the languages list. I think we have to show a current language (auto detected by text content) at top of languages too, to allow users see recently used languages immediately with no scrolling. For now you can enter language name in a keyboard when you open languages list.
Thanks for your comment, i've created issue to improve https://github.com/translate-tools/linguist/issues/389
It's good question. If a Mozilla people interesting for it - feel free to email me. As i know, for now a firefox translator is just a wrapper over Bergamot Translator while time a Linguist is a common purpose translation system for all major browsers, that embedded a Bergamot Translator as one of a great translator implementations.
For now Linguist had no reviews by influencers and it did not appears on reviews of a firefox addons blog unlike some other addons like proprietary Mate translate and open source TWP - Translate Web Pages. If we together make Linguist visible for a wide people, maybe Mozilla will pay attention for a Linguist too and we can integrate Linguist into a Firefox with all features it have
