Known Bugs

• Saved Workspaces are displayed in a combobox, which responds to SetOnAction, which is a change in selection model. As a result, if only one workspace is saved, it can only be reopened once, unless a second workspace is saved so the selection model can be changed effectively. This bug would have been fixed but for a nullpointer error that is thrown due to a bug inherint to the Java Fx combobox object
