“Import from robots.txt” appears only when a physical file exists; in virtual mode existing rules are imported automatically on first use. On install, an existing physical robots.txt is managed by default and its rules imported.
The current robots.txt is always shown on the Rules page (white background, scrolls on overflow); heading renamed to “Current robots.txt”.
robots.txt output consolidates user-agents that share the same rule under stacked User-agent: lines.
Rule descriptions say “selected” where they refer to the chosen crawlers.
After a bot-list update, newly added bots are checked in a rule only if its whole category was selected.
Bot category lists are indented with the checkbox in the list-marker position so wrapped lines hang-indent.
New rules are checked for conflicts before saving, with a dialog to fix or save anyway.
Settings: option to exclude XML sitemap link(s) from robots.txt (also suppresses the one WordPress adds).
If Yoast SEO is active, this plugin overrides it and controls robots.txt.
When in virtual mode while a physical robots.txt exists, the Rules page warns and offers to switch to physical (import the file’s rules), switch to physical (overwrite the file with the current rules), or delete the physical file.
