Hi Alfred, thank you for downloading our plugin!
We didn’t yet plan to promote it because there are a lot of lose ends to put together, one of them being the readme file that you’ve already noticed – which makes us even more happy to hear that there’s interest for it.
Freemius will show us some more detailed insights than what the basic tracking of wordpress.org is capable of.
Besides, there is a Pro version of the plugin which will be distributed through Freemius, but the first release is not out yet, it’s being tested at the moment.
Personally, the readme is one of the things that bothers me the most, but it’s the least related to the functionality of the plugin so it’s still not sorted out.
The word Free in capital characters will definitely be removed 🙂
Stay tuned for future updates and thank you for your feedback
