Hey! Sorry for the delay in getting back to you, I needed to mull it over a bit and also discuss it with the devs a bit.
You are correct in that it’s not possible and you aren’t missing something Long story short, due to how the backend functions with Cram + the sorting data, it wouldn’t really be possible to do it in a way that would visually look nice. I think the end result would just be a super elongated list, and it’s better just to have them sorted as they are now.
I’ll have to re-check later, but I think current bookmarks inside Cram are sorted by JLPT/Lesson order, so that may help out a bit? Also, the ‘Save to List’ feature coming soon may help if you find yourself only cramming the same set of items semi-frequently. That said, this is a good thing to keep in the back of our heads whenever we make more adjustments to Cram in the future as to how best to display and group stuff like this.
Super happy to hear you’re liking the new Cram feature! I always felt it was severely under-loved personally, so the new adjustments we made should hopefully get more people to check it out. Also excited for the Reviews 2.0 styling to move into Cram so it’s finally utilizing all of that good stuff.
Take care!
