[Feature Request] A site-wide unread notification variable

[Saterz]

Is your feature request related to a problem? Please describe.
Right now the top and bottom navbar both have an independent variable for the same thing: to know if the user has unread notifications. They both individually send a request to the database as well. This also means that I would need to maintain two versions of the same feature, which is not practical.

Describe the solution you'd like
To make a global notification that is available site-wide.

Describe alternatives you've considered
None

Additional context
None
