PRO version

I did PAY for the PRO version. It’s a great plugin. It loads well and quickly. Very few customization options though. The navigation bar uses WORDS, in ENGLISh ?? “NEXT” and “PREVIOUS” so we are locked out for other languages. I would love to ave ARROWS for the navigation, instead words. Could you guys let me know how to get this? I have submited a question on the official website as well. Also, the navigation bar and the thumbnails cannot be used in the same area. It would be really helpful to have an option in the PRO VERSION to have the thumbs in the middle. It only has RIGHT or LEFT. No option for MIDDLE. For designers, it really matters!! Please let me know the possibilities.
I would use this A LOT if there was just couple more options.
THANKS!!
