Editor Overview
The editor is where you draw and refine BPMN diagrams. It opens when you create a diagram or click one in the Diagrams list.

The Editor Screen
| Area | What it does |
|---|---|
| Tab strip (top) | Each open diagram gets its own tab. Switch tabs freely - unsaved edits in other tabs are kept. Close a tab with its x. |
| Title bar | The diagram name (click it to rename in place), the current version (v1, v2, ...), an asterisk when there are unsaved changes, and the save status ("Saved v4 at 07:14"). |
| Toolbar | Zoom out / Fit / zoom in, Auto layout, export buttons (PNG, SVG, PDF, VSDX), Delete, the Auto save toggle, and Save draft. |
| Palette (left) | The BPMN shapes you drag onto the canvas. Click the arrow at the top of the palette to switch between the narrow icon view and the wide labeled view. |
| Canvas (center) | The diagram itself. Drag shapes from the palette, click to select, drag to move. |
| Properties panel (right) | Shows the selected element's type, ID, and name. Collapsible. |
Working with Tabs
Open several diagrams at once - each gets a tab, and edits in progress survive switching between them. If you navigate to Editor in the left navigation with no diagram open, you get a welcome screen with your recent diagrams.
There is an upper limit on simultaneous tabs; if you reach it, close some tabs before opening another diagram.
Renaming a Diagram
Click the diagram title in the title bar, type the new name, and press Enter (or click elsewhere) to confirm. Press Escape to cancel.
Zoom and Layout
- - / + zoom out and in; Fit zooms so the whole diagram is visible.
- Auto layout rearranges the entire diagram into a tidy layout in one click. If you preferred your arrangement, press Ctrl+Z to undo it.
Deleting the Open Diagram
The Delete toolbar button deletes the diagram you are looking at, after a confirmation dialog. This is the same operation as deleting from the Diagrams list, and it cannot be undone.
