Hi Dobromir,
I am sorry for not responding earlier. I did not get notifications from here for a bit while I was migrating to a new mail client.
The plugin does work, at least on my websites where I use it and also based on the responses and feature requests I received from other users.
I apologize for the bad experience you made in regards to support. It was not my intention to disappoint you. Besides this forum here you can also use my support site at: Lewe.com Support
I just released version 1.4.0 of the plugin that introduces new interactive features like transposing on the fly and printing the renedered text.
Maybe you would be fair enough to recheck the plugin and change your vote here.
Thanks and best regards,
George
