Thank you for such detailed feedback — it genuinely means a lot to me as the developer.
You’re right; the balance probably does lean too heavily on manual clicking right now, just as you pointed out. I’ll think about how to improve it.
And the kanji on the icons — that’s a bug, so I’ll get it fixed. I’m Japanese, so I built the Japanese version first and then translated it into the other languages; I think something must have slipped through at that step.
