Thank you taking time and coming back with feedbacks!
- Landscape mode will be enabled in next updates, although it should already be working, will check.
- Feed was added later on, and is available right now on Android and next update shall have it along with profile refined pages and profile picture changes.
- Just noticed it, thanks for pointing out, will make changes in upcoming versions.
- Thanks for suggestions and I think Bookmarks/Favorites is great feature and I will work on this as soon as possible.
