The Configuration dialog is used configuring QBrew. There are four buttons on the bottom of the dialog. Pressing the OK button will apply all settings and close the dialog. Pressing the Defaults button will reset the dialog to default values. Pressing the Apply button will apply the settings, but not close the dialog. The Cancel button will close the dialog without applying the settings.
The Application directory control allows to you specify the location of the application. You should not normally need to change this. It should point to the installation directory or the filesystem hierarchy. Under Windows this should be the installation directory, under Mac OSX is should point within the application bundle, and under traditional Unix it should point to the filesystem hierarchy (/usr/local, /opt, etc).
The "Look and feel" control allows you to change the look and feel (theme) of QBrew. The "Use large icons" options lets you choose between small or large icons in the toolbars. "Show splash screen" lets you choose to display or not display the program startup splash screen.
The "Recent files" control selects the number of files displayed in the "Open Recent" menu. The "Enable autosave" controls set whether automatic saving of the current recipe is done, and how often. The "Enable autobackup" control sets whether recipes are automatically backed up. The "Load last file" control determines whether the previously used recipe is automatically loaded upon program startup.
The "Recipe Defaults" section sets some default recipe values. These settings only affect new recipes or ingredients. They include "Batch size", "Recipe style", "Hop form", and whether the recipe is "Mashed".
