It works. I wish it had a contrast checker so that I could either use different highlight colors or change the word color to make some text more readable.

Благодарю. Очень полезный плагин! Но мало настроек.

хорошее приложение. но имеется лишь один цвет-желтый. просьба добавить другие цвета

Hi... thank you for this work is usefull. I know every program need a lot of time. but can you develop customizable color for each word ? please .... i believe be better and more usefull for me

Nice and usefull add-on!
Lot of thanks to the author!
It could be a much more popular if has more features:

1. Enable/disable add-on with 2 clicks on toolbar icon.

2. Ability to add/remove/export/subscribe many vocabularies and enable/disable them.

3. Subscribe feature would be great! It is just ability to import vocabulary from URL of text file.

4. Assign custon color of highlited word and background/text of description - for each vocabulary separately.

I couldn't get it to work with words with spaces in them, i.e, English phrasal verbs such as "look for" or expressions like "hodge podge" for instance, are not highlighted, only single words. I tried to use double (") or single quotes (') with no success.

As most learners (if not all) would benefit immensely from learning such words, I was wondering if there is any chance you could implement such useful feature?

Thanks in advance.
