1. Translation is not yet. But it can be changed with certain custom code. However, if you are thinking to go for pro version, we have infinity scroll there, so these text are not needed.
2. Ya, the pricing is for a year. After that the pro version remains same it is not going back to lite version. However, after a year, you won’t have access to our plugin settings page, but the shortcode you have created and used will continue to work (Just can’t change those settings. Will keep on working as you have setuped). Also, no more updates are available after a year.
3. In Pro version you can control that via layout settings page. But for lite version, you need to hide them via css. If you wish i can sent those code for it.
