I will do my best to correct any reported defects as soon as I can make time, but please understand that this is side work. That said, I also use this plugin and am keen to ensure it provides the intended functionality. As to requests for enhancements, feel free to make these. I'll do my best to respond to your requests and, for those requests that I feel would benefit the majority of users, I'll get them on the enhancement list. I can't say just how quickly these would be implemented but funding the request would definitely move it up in the queue. If you have some of the questions or problems contact me on the Currency Converter Ruble
