### Open Issues
2+
3+
- Disabled FAB does not look disabled
4+
- Anchor button does not look disabled
5+
- No focused state
6+
- Icon buttons are not colored by theme
7+
8+
### TODO
9+
- Write README - looks like lot of overlap with checkbox README. Create common readme for setup
10+
- Move tests over (both unit and e2e)
11+
- JSDoc comments on all classes, consts
12+
- Consider supporting button[mat-outlined-button]
13+
- Add to universal app
14+
- Should each button type have a unique top level class? e.g. mdc-mat-icon-button
15+
- Consider if we want to add a "appearance/type" input to button, similar to form field (outline/stroked, flat, raised)
