Is there a way to check the total number of words to review in all courses?

The question is in the title.

In “Groups” page, sort your courses by a subject. For instance, if I sort my courses by “Japanese”, it list all the due questions for courses tagged as that language. You can then review all your courses together instead of reviewing one at a time. Useful for when a number of them have 1 to 3 reviews each.

Personally, I set my review limit to 100 which made reviewing much less tedious as well. You can do that in your personal settings.

In the group’s page, I just have "You haven’t created any groups yet."
Am I at the right place?
I’m learning more than 5 languages at the same time, and I have about several hundred words to review at the moment scattered on quite a few courses. Using the filter does not solve my issue.
I just want a single number that sums up all those numbers so I can estimate my workload and be on top of it.

Thank you for your suggestions.

Doh! I meant the “Home” tab which lists all your subscribed courses. The Group tab is for study groups like the one I have for SGJL or Japanese Drama Immersion. Sorry about that.

Ok, thank you, I see the summation for the category. I’ve indeed missed the button at the top which is useful.
But I still have to jump quite a bit between many categories: Russian, German, Swedish, Spanish, Arabic, Franch, Japanese, on a daily basis, and the workload is intense as it is with hundreds of words added per week, so an all inclusive number would really become handy.

I also started “Spanish Mexico” but mistakenly did one course of “Spanish Spain 3”, so it’s split now into two different categories. Quite annoying. It’s a big module with about 600 words.
I’m guessing and hoping that “Spanish Mexico 3” and “Spanish Spain 3” are quite identical, so I’ll be skipping the Spanish Mexico 3 module and just have a hole in the sequence.
