v1.5.10

v1.5.10 is a diagram and workspace polish release.

This release closes 3 issues: #60, #71, and #72.

added

• PlantUML preview: plantuml and puml code fences now show an explicit load preview action.
• PlantUML viewer: loaded PlantUML diagrams can open in the same focused zoom viewer as Mermaid.
• Persisted view mode: marka.md now remembers split, reading, or editor mode across launches.

improved

• Reading mode themes: the theme menu is available from reading mode, so palettes and text settings are easier to adjust while proofing.
• Context tray space: the context tray now appears only when files are staged.
• Default window size: new windows open larger for a more comfortable editor/sidebar/preview layout.
• Open With workflow: file launches and existing-window handoff are smoother.

thanks

• Thanks to @renwuli for requesting PlantUML support in #72.
• Thanks to @mshadmanrahman for the persisted view-mode request in #71.
• Thanks to @Durobert for the AI-agent workflow feedback in #60.
• Thanks to @hoiyada7-maker for the FILES, Open With, and single-instance workflow work that helped shape this release.
• Thanks to everyone testing the v1.5 feedback loop.

notes

• PlantUML remains explicit-load only, so local diagram text is not sent to plantuml.com just by opening a note.
• This release keeps the current signed updater and macOS private API setup unchanged.
