Description

While we using viewpager and drawer to switch to a new page, the new page will always loading data from internet even we have loaded before. Is it necessary to save the pages while they are in background and resume them when they are switched to front?

Research direction
Investigate the existing data loading patterns in the PocketHub app, particularly for feed views. Look at how ViewPager and Drawer handle page switching and where data is fetched. Consider implementing an in memory cache (e.g., LRU cache) for loaded feeds so that switching back to a previously viewed page shows cached data while optionally refreshing in the background. Review comments in the issue for suggested approaches and test with sample data.
