### Problem Description

Currently when picking any option from the menu on the left, such as trending, most popular , settings etc. it will highlight as you hover the option but then there is no indicator of which tab you're on afterwards on the menu itself.


### Proposed Solution

have the the menu highlighted or at least marked with a red underline similar to how it's done otherplaces on the app


### Alternatives Considered

any indicator of which tab you're on would help, whether its underlining or highlight or change in icon color etc
