Thanks for the extension! I would like to share some feedback. Sometimes, I am clicking on the magnifying glass icon unintentionally after selecting some text. Could you please consider: - moving the icon/button away from the selection a bit further; - not displaying it if the user does a triple-click, which is supposed to select the whole paragraph. In this case the magnifying glass appears after the first two clicks and gets pressed on the third click, if the user is not careful enough; - maybe using a different, more specific icon, like 'MW' initials or something. This is less critical, more stylistic opinion. Yes, you can get used to the magnifying glass but it feels a bit off at first.
Error handling response: TypeError: Cannot convert undefined or null to object at Function.keys (<anonymous>) at chrome-extension://gmhgdiamihghcepkeapfoeakphffcdkk/content.js:6:14942 at chrome-extension://gmhgdiamihghcepkeapfoeakphffcdkk/content.js:6:15256
I can be linked to the website immediately; that's great.
Best dictionary extension I've ever used!
Very convenient. You need to look a word up in the bar of the plugin to activate its double-click look-up mode in the first time.
WHEN I FIND IT HARD TO FIND THE REAL MEANINGS OF WORDS, THIS APP TOPS ALL OTHERS WITH THE RIGHT IMFORMATION FROM MEANING TO USING A WORD THAT MAKES ME LOOK LIKE I KNOW SOMETHING. THE APP IS A GREAT LEARNING TOOL.
Works well for me. Thank you for making this available! For other users - keep in mind that you will have to sign up for your own API key, as he mentions in the description. This demands a little bit of technical proficiency, but is not too hard
Very useful, thanks to the developer
Thanks. Superb great!
