Feature description

1.2.0

Added

Conversation shortcuts (#209)

the 'Conversation shortcuts' feature

random 'Conversation Names' keep appearing in the menu accessed by long-pressing the app icon, and they just keep accumulating - which is annoying.

Even for deleted or non-existent messages, the 'Conversation Names' remain and can’t be removed (bug?). also, 'CN' from the same numbers stacked on top of each other.

please make it optionable.

Why do you want this feature?

it would be nice to have the option to disable this feature for users who don’t use it.
