First impressions: feels rather unpolished

- text is too light and hard to read. Color contrast between text and background could be higher.

- up/down arrows do nothing

- plus button shows login dialog, but you can't register from there

- TP/EX/DE buttons are not in same order as their respective sections

- missing alt text on icon buttons, so it's not clear what they do (or rather, what they're supposed to do, since some do nothing)

- like button shows wrong cursor on hover

- buttons in settings dialog do nothing

- example has no code highlighting when present
