For those who don’t know about this, we are now making more of an effort to apply tags to posts so that they can be better sorted and retrieved. This is especially important in the Plugin Support area that is being used as an interim place for help with plugins.
If you want to quickly find all posts with a particular tag, you can open the menu at the hamburger icon in the top right.
Then select tags to see all the available options. You can sort them by name or frequency.
