My suggestion is to add a way to quickly navigate to certain places inside stories. You can currently only navigate by clicking the arrows, and if you want to go to a place somewhere in the middle of a long story, you have to click for a long time. I thought we could avoid that by adding a way to quickly navigate to a specific frame of a story, in the form of buttons in the open space to the right of the pictures. If you complete a story and look back at it the space to the right of the picture is no longer used by things like rewards and costs, so you will be able to use that space perfectly.
Example:
This is the introduction, which has 11 pictures, so there are 11 buttons to the right. We are currently on picture 6, so the 6th button is highlighted. if we wanted to go to picture 3 quickly, we would click the third button.
(I censored the picture itself in case that is required, but it is the 6th frame of the introduction of Begin City)
Alternatively we could have a progress bar under the picture, similair to what you have in the world overview, where you can click to go to a specific point:
Thank you for reading.
