With this release we introduce support for adding, modifying and removing links directly in the diagram. This is available in all maps whether they are organized in rows and/or columns or without grouping.
A link is added by clicking on one issue and then dragging a link to another issue.
A link can be changed by dragging either end of a link to another issue or deleted by selecting the link and deleting it.
Changes can be reverted by clicking the “Undo” 
button in the top right toolbar.
An “undone” change can be “redone” by clicking the “Redo” 
button in the top right toolbar.

Modifying a link
