Describe the feature you want

What's New section is important part of the app but it's burried under the humberger menu or by going to settings and manually adding it to the visible tabs. By adding What's New tab to the default tabs will make the app more easier to use (I would recommend making it the second tab).
There's subscription tab in the default three tabs but it's not the same, what's new section is your subscription feed.

Additional context

Here, i manually added "What's New" to the tabs and look how convenient it is!

How will you/everyone benefit from this feature?

People will easily find their subscription feed and new users will easily discover the feature and can access all their subscriptions in one place without going to each chanel individually to see their feed.

@SameenAhnaf Can I work on this issue?

[SameenAhnaf]

@Marius1501 Yeah, of course! You don't need to ask for permission. Just comment on any issue to let us know that you are interested to work on.

No, asking for permission is good practice for feature requests, because we might not actually want to implement that feature in the manner described, or we might even reject it after due consideration.

This usually isn't a problem with bugs, because they have to be fixed anyway. But even there, in some cases, we could have decided on a different approach, like with the dozens of duplicates that will be solved by channel tabs, instead of modifying the feed code.
