Possiblility to add a number to any given node which affect sort order of nodes on export
Possibility to add a number to any given node. If specified then the nodes on this level (with same parent), should be sorted in the HTML export, by this number. This way the creator of the MindMup could control in which order the nodes below any given parent is sorted.
An even better way to handle this, for more control and make it simpler to manage, is to mark any given parent in the MindMup and select the new menu: "sort order for export"
Then a list of the existing children for that particular node should be listet vertically, with the option to drag-sort the list. Of course this sort-order should not affect the way the children nodes are displayed in the MindMup. Only for use when exporting to HTML, PDF etc.
