Here is the auto-ignore script created by @Spurdosparde and shared here I have clumsily deleted the HSK specific content, so now it should work with any course.
To use it, paste any words you want to ignore between ‘single quotes’ and put a comma (,) between the words. In the script I have demonstrated that with the [‘plz ignore me!’,] lines. You can delete those and paste in your own.
You can use Greasemonkey on Firefox or Tampermonkey on Chrome to install it.
After installation, you will see an auto-ignore button on any level page on any course, click it and the script will go through your list and ignore the words it encounters. Do that for every level of the course. You will probably not want to constantly see that button, so after you’ve used it on a course, you can disable the script again.
The script looks at the first column (prompt I think). To have it look at the second column, change all 3 instances of col_a to col_b.
