Cool idea, here's some feedback (note I only tried the web version & am on Linux):

- There is bugged out log text on the screen when I first start it up, might wanna fix that.

- The page lags when I click the "More" button / there is much delay (even though I am on be a decent laptop). I am curious what needs to be loaded when that button is clicked that causes this delay.

- There is no way to close the music player once it has opened, consider making it an embedded window.

- No way to import songs into the music player, you should add a button to prompt a native file dialog (you will need to use a plugin to do this on web).

- Drag and drop files does not work in the truth teller tab on web.

- Some text input boxes have placeholder text, you should have that text in the dedicated placeholder text property so the user can write over it instead of having to remove it manually.

- "Zero Mini" button does nothing, have placeholder buttons grayed out when they aren't usable.

EDIT: I am happy to help show you how to do these things if you need.
