Startup Wizard - Kanji Page needs improvements

1. The "level/chapter" label gets obscured by the user's finger when they use the slider. It should go above the slider

2. Rather than 75 "steps", it should be broken into one step for each section.  This will result in 200+ steps for the JLPT lessons, so...

3. Include left/right arrows to move the slider by one tick

4. The "kanji you should know" should make it very clear that these are the kanji you should know HOW TO WRITE ALREADY, not just know how to read

5. Should add another list: "first lesson will teach you these kanji"
