Depends how you write your source text.  jEdit folds and Sidekick trees

differently than in the past, when Proof General was still there.

My main restriction when writing proof text comes from the document
generation to latex, where I want a readable layout. And this forces me
to have no lines longer than roughly 80 characters. As I have many
longer lemma statements, I need to format them manually into multiple

Keeping lines short (80-100 chars for source, 60-70 chars for LaTeX documents) is important, but it is still possible to put relevant information into the head-line of a fold or sidekick item, e.g. like this:

  lemma name: short_statement

  lemma name:

  definition name :: type_constraints
    where short_definition

  definition name :: type_constraints

Proper support for folds is still missing, but the general side-conditions for it are already given in jEdit.
