Biggest opportunity: “styles”, “stylesheet” and “toolkit” aren't earning a slot. You list them, but you're not in the first 24 results for those searches. WordPress.org counts only your first five tags, so free the slot for a search you can win.

of downloads still active

At least 10K of 241.3K lifetime downloads are still running, above 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 is fast and error free. It allows to easly add Less support to your WP theme. No needed configuration, just treat your *.less files like regular *.css in your theme’s directory.
