Button for Voicemail with Indicator for Unheard Messages

Is your feature request related to a problem? Please describe. Currently my Mother who has been using the BaldPhone app on her phone for several months has been having difficulty knowing that she has new voicemails. Yes, there is the general notification, but it would be useful to have a button that would immediately dial her voicemail.

Describe the solution you'd like Given that I am on the Home screen, When I want to check my Voicemail, Then I would like to press a shortcut button (like "Messages") called "Voicemail", that would open up the system dialer and immediately call my voicemail, with the speaker phone option toggled on and the dial pad showing by default. (the dialpad is so that I can easily enter my voicemail PIN)

Given that I am on the Home sceeen, When I have an unheard voicemail in my mailbox, Then I would like to have a indicator showing over the "Voicemail" shortcut icon (just like "Messages"), so that I know I have a voicemail that I need to listen to.

Describe alternatives you've considered On the "Dialer" screen, perhaps there could be a "Voicemail" button there? But still need to have a more obvious indicator on the Home Screen that indicates an unread email.
