The editor is split into 2 main areas: the stations overview to the left
and the active station to the right.
In the stations overview, all stations of this quest file are listed.
(You can create multi-chapter adventures by connecting more then a single quest file, but the editor will only let you edit one chapter a time.) If you right-click a station, you can select from some options in a context-menu.
The content of the selected station to the left can be edited to the right in the station content area.
The station content is splitted into three tabs:
"Editor", "Source" and "Preview". These are different edit modes for a station and you may want to switch around these, or maybe you just want to use a single, preferred tab.
