Thanks for reaching out. Currently, renaming the files within the GoPro App is not a feature.
Also, the app will follow the orientation of your device except for the Home screen. If you cannot rotate your device to display video horizontally, it is likely that you have Screen Rotation disabled on your mobile device. The way in which this is enabled or disabled varies by device manufacturer. Generally this setting is found in the main device settings. If you are unable to locate it, please consult the device manufacturer for assistance.
If these are the options you'd like to see in the GoPro App, you may leave your feedback at https://gopro.com/en/us/feedback.
