Thanks for your report. While this is not an issue, it will not be accepted. This is more likely a suggestion instead of a bug: This area is not clickable by default in our app. Even though in Steemit it is possible, both are different platforms that cannot be compared each to the other.

Filtering by tags is already developed but the update has not been sent yet. Also, even in the next update, this area is not clickable yet. Hence, it is more a suggestion than a bug report.
