seanos, there are two page indicators with Mantano. One pops up on the bottom with the rest of the menu options including settings when you tap the center of the screen. That one can hide text.
But there is also a static page indicator that you can enable in the settings. It is always visible and does not hide text. I would be surprised if this one is not on the free version of Mantano.
I agree that a static battery indicator and the time would be very helpful. I have already contacted the developers of Mantano to ask for that. Maybe if more people request these enhancements too, they will implement them!
Here is their website where they can be contacted:
