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.
