Unfortunately the menu items were linking to K2 items, and plugin didn't work. I wrote the developer and he said adding K2 menu items has different logic behind it so the plugin doesn't work. However, he promised to see what he can do.
It took two days and he came out with a new version - this one works with K2 and helps me a lot. Very fast and helpful! Thank you!
This plugin is very useful, it makes editing almost everything very fast. No more waiting for edit page to open and scrolling back and forth a long list of items. Recommended!
Thank you for your review. About your suggestion: Please understand, that this extension is a content PLUGIN. It is by design working within the Joomla main content (i.e. an article). A fish does not need to get improved because of it's unability to fly ;)
To show a slideshow on a module position, please use an extension developed as a MODULE (plugins are marked with a small icon showing a "P", modules with an "M" in this directory). Doing so will save you a lot of time and help you to keep the structure of your site's backend clean because you do not need two extensions (the plugin and the module to display it) but just the module itself.
