The matrix editor now has a vertical header with support for custom headers and the ability to assign matrices to the vertical and horizontal headers. The info window of one item (matrix, function, etc.) now contains links to the connected items and menus, allowing navigation. A GUI settings dialog was provided. It is now possible to open matrices with over one million elements due to the implementation of a virtual table.
