Feature description

Currently, to copy part of a message, the process is:
Select Message → Three dot Menu→ Select Text

This is not very user-friendly.

A better approach could be:

• First long press to select the whole message.

• Then long press again to enter partial text selection (As In Telegram).

I belive this would make copying text much easier and more intuitive for users.

A floating toolbar when you single tap on a message would be more easier (like in textra) : you can see all available actions with one tap
