It gives a smooth UX. It would be even nicer to see 3 or 4 suggestions.
The first one isn't always the best match. At least for Hungarian.

The extension works very well, although the icon does not appear on some sites. Also, when accessing the settings menu of the plugin, I found it difficult to customise the key combination. Apart from these aspects, I found no major difficulties in using the add-on. I recommend everyone to make use of this tool for instant translations, without having to leave the browser.

Same bug: on sites where there is text input in the form (for example github), after entering text and scrolling down there is a ghost frame with text.

Overall, this add-on is great, though it has some room for improvement, here are some suggestions:
An option to display the translation pop-up immediately upon text selection.
The audio to help pronunciation is good, but the TTS engine could be better(it's using speech synthesis capabilities provided by the operating system)
An option for a more minimalistic layout for the dictionary to avoid excessive scrolling.

As other users reported, there is still text box ghosting on many sites. It is a pity that developers totally don't care about it.

Exactly what I was looking for. Unfortunately the shortcut does not work for me (German keyboard layout)

IT's finally here, loving it, but it is missing dark mode. Once dark mode is available, it will be 5/5 stars
