You can set preferences for project containers, as well as for the font to use for multi-line properties from the general preference page.
To modify your General preferences:
Select Window | Preferences
Expand the Team node, and select Serena Dimensions. The general preferences appear.
Choose whether to show project containers in the Serena Explorer view, and choose whether to create new projects by default in project containers.
Select the Show Single Eclipse Projects in Explorer option to display Eclipse projects that are mapped 1:1 to Dimensions CM projects, in the Serena Explorer view.
If your Smart Card software is installed to a different path from the Dimensions for Eclipse default location, change the Smart Card library path to the correct location.
