Today I just completed the Russian course, which means that I've now completed Spanish, German, and Russian courses (although new words have been added to Spanish and I haven't quite gone through them yet.)
For the future, I'm less interested in adding more words and more interested in getting more languages added. My top priorities would be Portuguese, Chinese (Mandarin), Japanese, Hindi, and Indonesian/Malay, but I would also be interested in Turkish and possibly other languages. Which one is added first is less relevant to me: I think Lingvist is such an efficient tool for me that I'd probably choose to focus on whatever language were added next.
The reason I want things prioritized in this way is that it is often very hard to get from 0 to functional in a language, whereas once I've gotten to the 3000-4000 mark, I'm kinda functional...I can stumble through conversations, express myself, and look words up in a dictionary, and that's "good enough" for me to go the rest of the way by immersion.
Starting out cold though, is very hard. And this is where I find lingvist indispensible...getting me that early vocabulary and also helping me to wrestle with the meaning through the passive exposure, listening and reading sentences and doing whole-sentence level thinking in my head.
I don't know what kind of resources Lingvist has and I don't know why they haven't been adding more languages, but I'm starting to get frustrated that no more languages have been added recently. I have paid for a year subscription now for the second year, but I'm quickly exhausting what Lingvist had to offer. I paid in large part because I want to support Lingvist and fund its farther development. If no new Languages are added, I most likely will cancel my subscription at the end of my current one. And I will feel considerable frustration if doing so. I really want to see the team get their act together and get another language launched.
How hard can it really be?
