    ### Use canvas
    To start with tab, you need to prepare a plot by clicking the
    `To Canvas` button at other different tabs. A screenshot of a plot will be added
    to the `Images/ Plots` section on the left sidebar.

    Simply drag a plot you want to canvas and start your creation.

    - `View`, `Canvas` menus provide some options to change the canvas.
    - `Help` menu has some detailed instructions.
    - Use `File` menu to save your work.
