@Wikinaut I'm afraid "no more options" applies here.
We would much rather improve upon the Explore feed, and make it incrementally more useful and engaging for our readers. The app should automatically resume at your last-read page, if you come back to it in less than 24 hours (if it doesn't do that, let us know). The feed also contains a "Today on Wikipedia" card that takes you to the Main Page of your Wiki, if necessary.
If I may ask, which portions of the Main Page do you find the most useful? (i.e. what do you find missing from the feed?)
