Hi @schmallan, thanks for the suggestion! Great to see that you're interested in working on this.

It unfortunately does not align with the current direction for the PDE.
Code folding like you are suggesting is very helpful for more advanced users of Processing but is somewhat confusing for beginners, especially if it can be done on accident. Instead we are planning to expand the possibilities to use editors like VSCode (see #1115) and IntelliJ IDEA, which already come with code-folding support out of the box.

For future reference, this idea is a duplicate of #426.
