The menu will automatically expand once a workspace has been created/opened. It contains all menu items for accessing the entry forms (Database|Access Data|…), Edit to search and edit certain parts of your settings, Tools to access various data retrieval and manipulation tools, Report to produce portrait and landscape data reports and Charts to produce various time-dependent, chemistry, logs, construction and other charts.
The buttons provide access to the most commonly used entry forms. A little down-arrow next to the button allows access to more than one function with the same button by opening a small menu.
