This is now supported.
Saved words in your Word List now get underlined when they appear in texts you read in Chinese, and the same applies to Traditional Chinese, Japanese, Thai and Cantonese.
The setting is off by default, so to switch it on:
- Refresh your Readlang browser tab
- Open a text to read
- If the sidebar isn’t visible, click the button at the top right of the page to open it
- Click to open the Settings tab within the sidebar
- Under Auto-Highlight Words, select “All Your Words” (or “Ready To Learn” if you’d rather only see the words which are due for review)
Please let me know if you notice any problems with this.
