Hi, It's a very nice extension, thank you! Can you please add a Keyboard shortcut option to Activate the Bubble? Because sometimes I just want to search some word which suddenly come out from my brain.
Request: 1. A history of all words looked up; 2. An option to save words for later.; 3. Merriam-Webster as a source. 4. Option for showing synonyms of the words.
10 out of 10. Exactly what I'm looking for.
Обалденное стильное и удобное приложение! Было бы здорово добавить Яндекс.Перевод и Яндекс.Киртинки(Поиск)
Apenas la eh usado un poco pero hasta ahora se ve bastante prometedor, la función del PDF Reader es magnifica y la gran variedad de recursos que te da para el entendimiento de una palabra lo hace muy versátil y practico!
Thank you for the extension. I would like to see Brave search support as a source please.
Thank you. It's very beautifully designed and very easy to use. Please keep up the good work.
Редко оставляю комментарий, это просто волшебство какое-то!))) Огромное спасибо, за чудесное расширение, которое мего-удобное!
Great product
Amazing extension overall Just ran into a bug which I wanted to bring up. The extension is breaking some google spreadsheet websites, causing the scrollbar and whole page to freeze up. Examples include sites like <https://releases.moe/> and <https://index.fansubcar.tel/>. Edit: fixed now!
