New version of Cayra can be dowloaded from here.

What's new:

• Nodes now have volume (and we think, they look better that way :))
• There're no more shadows under nodes or links
• Nodes are created at the place where you double-click to create new node
• "Undo" started working for undoing linking
• An option of deleting links has been added
• When you try to save an edited read-only file, a dialog window with explanation of the problem appears. User may select saving map in another file
• Have fixed character bugs in search field and in the Node name
• Icons and icon groups are updated right after changes are made
