In Audacity 2.4.2 and earlier, when a project is saved, an entry is added to the audacity.cfg file:

[SaveAs]
Path=<last used path>

On closing and relaunching Audacity 2.4.2 or earlier, "Save Project" defaults to "<last used path>".


In Audacity 3.0, the [SaveAs] entry is not written, but is read if present.
This is bad news for upgraders as it means that the default Save location is stuck at whatever was last used prior to upgrading.


During QA discussion about the above bug, it was agreed that it would be very desirable to:

1. Provide consistent handling of default paths for Save, Open, Import, and Export.

2. Provide an option in "Preferences > Directories" where the user may select a default directory for each of; Save, Open, Import, Export, or if preferred by the user, default to the last used directory for that action.

One example of a possible GUI that has QA support:
-----------------------------------------------
Default folders ("last used" if not specified):
File Open: [__________] [Browse]
File Save: [__________] [Browse]
Import:    [__________] [Browse]
Export:    [__________] [Browse]
-----------------------------------------------
