Biggest opportunity: Swap “theme editor” for “inspector”. “theme editor” isn't earning its slot: you're not in the first 24 results for its own search. “inspector” sits at #6 untagged, close enough for a declared tag to move it up. All five slots are taken, so one has to go.

1.6%

of downloads still active

At least 100K of 6.2M lifetime downloads are still running, above its category: the median Uncategorized plugin keeps 0.6%, across 17,766 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 4 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.

    The best CSS editor I have come across!Stable, lightweight VAST improvements for workflow with their editor with, transform preview and inspector. Overall a great and simple plugin that I wish I knew about years ago – I was using other CSS solutions that were trying too much or simply didn’t work half the time. SiteOrigin Nailed this one with an elegant solution to one of the most popular issues of wordpress – editing CSS in a fast, effective and convenient way! Suggestions for improvements Resizing the CSS panel in Expanded mode Create additional CSS files, that prints after the main file – this would allow better structure and faster navigation. Thanks in advance

    It really makes it easy even for developers by showing the selectors and class names! It really helps me a lot. Thanks!

    I don’t know what I’d do without this. I used to struggle writing styles in WordPress, mainly because it was difficult to target a particular property using the browser inspector. But this makes the whole job dead easy, and it’s free!

    thecanuckian wrote a year or so ago “where has this been all my life?”… I can only repeat. This is one of the most useful WordPress plugins I know. It will shorten the editing time and one can also learn something in coding. Thank you very much for creating it and taking care of updating it. Best regards, friends!

    This is one of the best CSS plugins out there. It’s WAY better for custom CSS than the built in WP way. While writing this review, I made two feature requests which would bump it up to five stars. One thing I’m personally missing is a sort of CSS guide. As in, links to the W3C page of that properity for people to read up upon.
