Blocks Media view
by Bub·2 months ago
This plugin block me from viewing my media files when I am, for instance, trying to add an image block to a page. Except for this I think it is an excellent plugin. My work-around will be to disable this plugin while adding any image media and re-enabling it when I am done.

So simple yet works perfect!

İt’s so easy to use and does the job as described.
Useful but doesn’t know modern properties
by ellissei·3 months ago
Simple and useful, but modern CSS properties like clamp(), repeat(), margin-inline, or less common units like dvh throw syntax errors. For beginners, this can be really confusing.
Fantastic!! But abandoned??
by sintow·1 year ago
Have been relying on this plugin for several years. The problem is that it appears to have been abandoned, leading to warnings on popular security sites and plugins. It would be so great to have it updated again!
Works out of the box
by ILIAS CHATZISTOGIANNIS·2 years ago
No settings needed for this plug in. It just works. Great choice for customizing footers and headers.
