Been working on copy-paste functionality for my notes app. It may sound a bit strange as you might expect this to just work by default, but because of the way I handle text editing in the app, it does not work out of the box.


My notes app is block-based and because of this, each text block is its own text view. This means, a note document includes multiple `NSTextView`s (one for each text block). This makes copy-pasting from multiple blocks quite complicated as these text blocks are completely separate - they have no connection to each other.

This is where my ‘sequential text view’ hack comes into play. I figured out a way to connect separate `NSTextView`s to allow performing text selections across multiple text views, and then I override the default `copy()` function with custom logic to stitch these text blocks together while keeping the text styling/formatting.

So far, copy-pasting works for text, heading, and list blocks. Tomorrow, I will make it work for table, quote, and code blocks.
