Enhanced Directories preferences
Default folder locations have been added enabling you to specify the folders to be used for each of the Audacity actions: Open, Save, Import and Export.
If you set a default folder for any of those actions Audacity will always offer that folder location when you invoke that action.
If a particular action's default folder is left blank (default setting) then Audacity will offer the last-used location for that action.
The default setting is for all to be blank.
See Directories Preferences for more details.

Import and Export of Macros
Import and Export of Macros has been added to the Manage Macros dialog.
