Is there a reading ruler?

Hi, all! I have eyesight issues and ADHD so I really appreciate the ability to change the colors and fonts in the ebook viewer, but sometimes I lose my place on the page. The iOS kindle app has this thing called a "reading ruler" that you can place anywhere in the page and it stays still while you scroll the text through it. It will highlight a few lines of text, allowing you to remember where you were last reading. This is immensely helpful to me, and I wonder if there's any way to do it with calibre?

Not sure exactly what you mean, but you can probably have a floating hovering box over the left margin at the vertical center of the page using the extra css settings in the viewer. Then you switch the viewer to flow mode and scrolling will scroll line by line while the box will remain floating at a fixed position.
