Biggest opportunity: Add “multisite” to your wp.org tags. You rank #19 for it without listing it, close enough for a declared tag to move you up. WordPress.org counts only your first five tags, so with 4 listed it's a slot worth spending.

of downloads still active
At least 100 of 15K lifetime downloads are still running, in line with 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.

wp.org is where the directory puts the plugin for that search. On merit is where it would sit if results were ranked on rating, support and updates, without the install boost. The last column is how far the wp.org position moved, from our first reading in the last 90 days to the latest.
| Keyword | wp.org | On merit | wp.org move, 90 days |
|---|---|---|---|
| multisite | #19 | #23 | up 4 |
| custom css your tag | #19 | #22 | up 1 |
| css customizer | #17 | #19 | up 3 |
| css your tag | Not in the top 24 | ||
| custom design your tag | Not in the top 24 | ||
| customizer your tag | Not in the top 24 | ||
10 searches this plugin appeared in over the last 90 days, 3 listed. 7 left out as unrelated or noise (years, numbers, stray words). 3 of its tags aren't in the top 24 for their own search.
What to do about it

Title says it all
Read on wp.org ↗ - ★★★★★ Bigue Nique5.3y ago
Works perfectly, allows admin to tweak their site’s CSS. I found that this plugin doesn’t need to be activated network-wide: you can let admins decide to activate it whether they need it. The custom CSS rules will stay even when the plugin is deactivated. They can always be edited by a network superuser. This topic was modified 5 years ago by Bigue Nique.

Very useful. I support a great many sites and several of the individual site admins were keen to tweak the CSS. This is a great solution!

This works very well to allow my site admins the ability to use the built in CSS editor. We were using a separate plugin for this which has been deprecated. Thank you so much for this great plugin.
