[Blades in the Dark] Seeking documentation, or answers to a few questions

I am just starting (as a player) and I am really impressed with the Blades in the Dark character sheet already. Is there detailed documentation for it somewhere? Or maybe there is a forum thread to report/request changes? If not, maybe folks can answer these questions: Is there any way to change the font for the Notes (lower right). It's really difficult to read the default font. Can I turn off the lines in the Notes field? They don't scroll with the text, which also makes it difficult to read. In the settings (gear icon) there is a text field labeled "Image to show alongside chat rolls". What can I put into this text field, what images are available? It is just a URL, or a reference to a built-in library of images? If there are any hidden features I'd love to know about those too! The Torg Eternity sheet is full of those. :-) Thanks in advance....

If you want to tweak the appearance of the sheet, or R20 in general, I'd highly recommend installing Stylus or a similar extension. The Stylening thread is a good place to start - you can change pretty much anything you can see outside the canvas itself. This only takes effect for you - you're not editing the page, just how it's styled in your browser. I'm not familiar with the sheet, but I'd say that text box is just for a URL, you can test it with this <a href="https://s3.amazonaws.com/files.d20.io/images/150119084/bqUDdEvKzLySYAC0MSNBoA/thumb.jpg" rel="nofollow">https://s3.amazonaws.com/files.d20.io/images/150119084/bqUDdEvKzLySYAC0MSNBoA/thumb.jpg</a> and see if it does anything :)

Yes, turns out the text box is just for an URL, but it's fussy and not all image URLs I tried work. But I got the basic idea. Stylening looks cool, I will check that out. Thanks much!

This is a nice feature I might recreate on other sheets, seems like a nice little thing. Pity you can't display Images from custom url on the character sheet itself, like the character portrait/avatar.

By the by, I noticed that, unlike most other things I select, which turn red, one of the deadly allies (down triangle) remains black. Is there a secret (or not-secret) reason for that?
