    A highlighter stroke has one width, and Rainbow and Galaxy ink become one color. Elbow connectors become straight, and reactions on notes become a line of text in the note. The background color is left out, and an object the export shows as a placeholder stays one. After the import, a message lists anything the board did not bring across.

    SQLBI Whiteboard keeps each board in a file on your PC and has no real-time collaboration. Compare lists the differences from Microsoft Whiteboard.
