Biggest opportunity: Add “theme”, “development tool” and “practice” to your wp.org tags. You rank #4, #5 and #5 for them without listing them, close enough for a declared tag to move you up. WordPress.org counts only your first five tags, so with 3 listed these are the slots worth spending.

of downloads still active
At least 20K of 2.6M lifetime downloads are still running, in line with its category: the median Uncategorized plugin keeps 0.6%, across 17,767 plugins.
Downloads count every update, not just first installs, so older and more frequently released plugins read lower. Compare against other Uncategorized plugins, not across the directory. wp.org reports active installs as the bottom of a band, so the real rate is this or higher.
This plugin shipped 2 releases in the last 12 months, and every existing install that updated counted as another download. wp.org publishes no split between first installs and updates, so we show the raw rate rather than guess at one.

Great plugin and support! It works well!

I heard good things about this plugin until I used it. It says my theme name and text domain/slug do not match. They do so why is it flagging a non-existent error?
