Sounds awesome. Loving the sample sentences. Can’t wait to see the finished product. Maybe you want to go in and make a course together with @miaomiaopurr?—going to make one on Ronja Rövardotter, I believe.
Like I said above, you have to read Aniara. Even if you’re not a poetry reader, you’ll like it.
I’ve only read Bröderna Lejonhjärta so far (yes, it also has underlined vocabulary). My only exposure to other Astrid Lindgren is via audiobooks.
I love poetry, so maybe I should look into this “Aniara” business.
Thanks for sharing the spreadsheet of your course in progress. I really look forward to trying them out when they are ready. 
I’m curious if you can recommend any sources for audiobooks in Swedish? I tend to rely on audible.com (US version) and while they have a fair selection of several languages, their Swedish offerings are really disappointing. Any ideas would be appreciated!
I’m looking forward to the hitch hikers guide course. That’ll be fun once to do.
