It is an oversight. I should have made wireframes for this and think it through. This stuff takes time and I'm pretty much by myself doing everything, coding, designing, and thinking all the use cases and scenarios. Yet it's my mistake because I end up wasting hours coding something I'll throw away anyway because it wasn't well thought out. That's what sucks. I keep telling myself to just hold off the keyboard and think through what the screens look like. Sigh.
I think the reason I merged Restudy and Learned is that I was trying to optimize the mobile view and this seemed like a good way to save space at the top of the page.
In fact I started by removing the "next 10 failed card" summary that was in the sidebar. The Study box was optimized to just show "Next : (kanji)" instead of the next 10 failed cards. And so once you started learning cards, both boxes said the same thing. The Study "NEXT" didn't have a purpose, because "Add to LEarned List" already takes the user to the next failed kanji. Hence, I had the idea to merge them.
And to be fair you could definitely review the learned pile, before studying more. But I agree it's less flexible.
In theory you could continue again from the Restudy List, except it doesn't exclude the learned kanji... so it's a bit tricky to find the first failed card to continue from (assuming you clear them in index order). And THEN you would continue "Add to learned list ". But that part is definitely not intuitive nor practical.
A good point here is that what is essentially missing, is a way for you to find the first failed card, so you can continue the cycle of "Add to learned list". That is the main issue. A secondary issue, is that there is no visible list anywhere of what's currently sitting in the learned pile. Point being maybe the current design is not all bad, but something's missing
At this stage I'll leave it to the users to tell me it's something they want fixed.
This happens on Github, with an Issue, then it can collect potentially other comments, and at least there is a recorded conversation in the right place to follow up. And then If I decided to do something i can post mockups there and have a modicum of feedback since participatns can be notified. I can't do this on the forum.
EDIT: this would be the conversation to continue, I can potentially re-open this issue
