Cornerstone

How well this listing is tuned to rank in WordPress.org search, on the factors an owner controls. Not popularity, optimization.

Directory rank vs rivals

wp.org popularity rank over time · higher is better · when a rival's line climbs above yours, they've overtaken you

How often this plugin actually ships. A steady rhythm is the maintenance signal a single "last updated" date can't show.

Share of active installs on each version of this plugin · 87% run the current release. Green is the current release; a big slice on older versions is a user base that has stopped updating.

Refined from the date this plugin crossed into its current band.

No paid tier is visible, so we don't put a figure on revenue or sale value: that would be guessing. The install base is a real asset to an acquirer, just not one public data lets us price.

   I had a few difficulties using the plugin. It is important to be familiar with the template technique. Thanks to the friendly and patient support, I was finally able to set everything up as I wanted it. Thank you for this plugin!

   Why should installing a plugin be so hard! 1) find Cornerstone on the plugin store. 2) click install 3) click activate 4) find it on your list of installed and activated plugins. All works fine. But does absolutely NOTHING. No menu items, no settings link. So you could start trying to figure out why, but then that will waste another half an hour. Because there is nothing to discover. No warning messages, further hints at what you ought to do. It is not going to do anything. So don’t waste your time. I finally downloaded Live Composer instead. Immediately it worked. That made me feel that it was not me after all. To the developers: Instructions please guys. I am sure it’s great when it works. But do not assume new users to the plugin know how to navigate the installation procedures. This topic was modified 9 years, 5 months ago by fabsoftware.

   I found the idea of this plugin quite useful so I was tempted to give a five star rating. But the permalink function is not fully configurable and does not work without trailing slashes which in some cases might be wanted. Since I found that a central part of the task the plugin should be used for is not functional I only gave it a 3 stars rating.

   Thanks to cornerstone and in combination with the theme X I’m able to mockup designs together with my clients, because it’s so easy and fast to use.

   it’s an effective plugin for sorting posts on page basis instead of categories and with its options,integrates nicely. I also found good support by the author. Check his other plugins too. -Cris.
