Parker 0.4.3

Collapsible sections

Fold a heading and its whole section goes with it, down to the next heading of the same or higher level. Fenced code, quotes and tables collapse too, and any line folds whatever is indented beneath it — which is what makes nested to-dos and lists fold.

A chevron sits in the gutter with the line numbers: visible on hover while a fold is open, and always visible once it is closed, because a fold that hides itself is a trap. The folded line's number takes the accent colour, and a badge in the text counts the hidden lines. ⌘⌥[ folds, ⌘⌥] unfolds, ⌃⌥[ and ⌃⌥] do everything at once.

The editor remembers

Each pane now keeps one editor with one state per tab. Switching tabs used to rebuild the editor from scratch, which meant losing the cursor, the scroll position and the undo history every time. All three survive now — and so do your folds.

Note on first launch

The app is ad-hoc signed, so macOS shows a Gatekeeper warning the first time you open it, and asks again for access to your Documents folder after each update.
