PenEcho Files

What's Changed

• Professional diagrams beyond flowcharts. Create architecture, UML, sequence, BPMN, data, engineering, scientific, medical, financial, geographic, and other domain diagrams with editable professional source. Supported formats use on-demand local renderers; specialized formats can return complete HTML without forcing every request into one renderer.

• On by default, with a smaller prompt footprint. Professional Diagrams starts enabled and can be turned off from Plugins. Only its compact capability guide is sent to the model; full CSS and renderer dependencies stay local and load on demand.

• Refine plugin widgets by drawing on them. Use the Pen to draw or write the requested changes directly over a widget returned by a plugin, then click the AI Refine button that appears to generate its upgraded replacement. This workflow applies only to plugin-returned widgets.

• Device or PenEcho server storage. Save canvases only in the current browser, or on the computer running PenEcho so other authorized devices using the same server can open them. Saving first confirms unfinished canvas controls so text boxes, diagrams, and widgets are included.

• Clipboard, text, and extensible plugins. Read text or images from the system clipboard directly into native canvas controls, copy returned text, formulas, and professional diagram source, and reselect editable text boxes with Hand. Built-in and private plugins can be copied into a custom plugin, with optional CSS loaded only when that plugin is used.
