Thank you for your kind words!
I’m afraid we can’t do the captions nor the descriptions. We had attempts to make a more powerful autocomplete by using post content and other fields, but there are many issues with that – some performance related and some others. Because how the plugin is priced and works (one time fee, and runs on your local server), there are some things we have to consider – especially performance related – before we add any new features. This is something we probably won’t be able to implement any time soon.
If the plugin was subscription based with on-demand usage and payment, we could basically do anything, as our servers could handle the queries. However the price could shoot up from hundreds of dollars to thousands per month – instead of the current very low one time license.
