Mindmaps

Mindmaps is an optional workspace app that gives you a full visual canvas for building mind maps, flowcharts, and diagrams. You can add shapes, connect them with styled edges, upload images, annotate with sticky notes, and group areas with section containers. Every canvas auto-saves as you work.

​

Enable Mindmaps

Mindmaps is not enabled by default. A workspace Owner or Admin must turn it on first. Go to Settings > Arca Apps, find the Mindmaps app, and click its toggle. Once enabled, a Mindmaps entry appears in the left sidebar for all workspace members.

​

Create a mindmap

1. Click Mindmaps in the sidebar.
2. Click New Mindmap in the top right corner.
3. The editor opens immediately with a blank canvas and a single starter node.

​

The canvas

The canvas is an infinite workspace. You can zoom in and out, pan by dragging, and rearrange nodes freely. Every change is saved automatically with a short debounce; a Saved indicator in the toolbar confirms the last save.

​

Tool modes

Two tool modes are available in the bottom toolbar:

• Select (cursor icon): click and drag to select nodes; drag a selection box to select multiple nodes at once.
• Hand (hand icon): click and drag the canvas to pan without accidentally selecting nodes.

Press S to switch to Select or H to switch to Hand from anywhere on the canvas.

​

Adding nodes

The toolbar along the bottom of the canvas contains all the node types you can insert. Click any button or press its keyboard shortcut to add a node near the center of your current view. Nodes are placed automatically to avoid overlapping existing content.

​

Editing node labels

Double-click any node to enter edit mode and type a new label. Press Enter, Escape, or click outside the node to confirm.

​

Deleting nodes and edges

Select one or more nodes or edges and press Delete or Backspace to remove them.

​

Connecting nodes

Hover over a node to reveal the gray connection handles on its edges. Drag from any handle to another node to create a connection. You can create a connection between any two nodes regardless of type.

​

Edge styles

The top-left panel provides three options to control how connections are drawn:

• Smooth: a smooth curve between the source and target handles.
• Curved: a gentle arc with a single bend.
• Straight: a direct line between handles.

Switching the edge style updates all existing connections on the canvas immediately.

​

Floating edges

Enable Floating edges in the toolbar to let connections attach to the nearest point on each node rather than to fixed handles. This is useful for complex diagrams where rigid handle positions get in the way.

​

Arrowheads

Three arrowhead options are available:

• None: plain line with no arrowhead.
• Open arrow: an open arrowhead.
• Filled arrow: a solid filled arrowhead.

​

Canvas controls

The controls panel in the lower right corner of the canvas provides:

• Zoom in and Zoom out buttons.
• Fit view: zooms and pans to show all nodes at once, accounting for the toolbar at the bottom.

​

Alignment guides

When you drag a node, alignment guide lines appear automatically when the node’s edges or center align with another node on the canvas. This helps you keep layouts tidy without manual adjustment.

​

Keyboard shortcuts

​

Canvas limit

Each mindmap supports up to 500 nodes. This limit is per canvas and prevents performance degradation on very large diagrams.

​

Rename a mindmap

Click the title in the toolbar at the top of the editor to edit it inline. Press Enter or click outside the title to save. Press Escape to cancel.

​

Delete a mindmap

From the Mindmaps list page, click the menu on a mindmap card and select Delete. You will be asked to confirm before the mindmap and all its nodes are permanently removed.
