Getting started
A tour of the editor
Top bar
The name of the wireframe, its save state, then the tools: Move, Hand, Frame, Shapes, Text, undo and redo, and Export.
Left panel
Two tabs. Layers shows every frame and layer as a tree. Components is the library, with search.
Canvas
An endless canvas holding your frames. Scroll to pan, hold Ctrl and scroll to zoom.
Right panel
Properties of whatever is selected. With nothing selected, it shows the theme of the whole wireframe.
