The premise of this plugin is really great - create listings without having to create posts/pages.
However, there are no shortcodes, hence the only option is to install the instance in a sidebar.
Styling of this sidebar widget is really great, looks awesome. However, when I made a selection based on the state I put in for my test listing, all I get is a "hello world" page with comments enabled. I have comments disabled globally, so this is not acceptable.
A severe problem (at least with Arjuna X theme) is that when this plugin is installed, EVERY page transition in the website flashes to a completely blank white screen - not acceptable.
I think this will evolve to a really great plugin with some work.
