Saved defaults

Save as default keeps everything you chose: content types with their items (or filters, on the classic screen), options, format, file name, media files and Playground themes and plugins. The Export screen opens with them, and Reset to defaults goes back to them. Nothing else is kept: choices you don’t save are forgotten when you leave or reload the screen.

Whose defaults

Settings → General → Defaults are saved for:

• Each user (default) — stored in user meta; anyone who can export saves their own.
• The whole site — one set for everyone; saving or clearing it needs manage_options.

Both screens

• New screen: Save as default in the header; Reset to defaults goes back to them, and Clear defaults (active once the choices are the defaults) forgets them.
• Classic screen: check Save these choices as my default before downloading. The classic screen starts filled with the defaults too.

Clearing

Clear defaults in the Export screen’s header, Clear saved defaults in Settings → General, or the eizport/clear-export-defaults ability.

What is checked

Defaults are sanitized when saved and again when loaded: unknown types and items, options that are never exported and themes or plugins no longer installed are dropped. Filters keep only the values that are set.
