This has been ask for repeatedly in different support tickets. Please make this very basic feature available! Chomp is otherwise very nice, but something as simple as copying a verification code in a text message is a pain.

Please allow this option like most sms apps

So important for copying one-time codes or other information like address etc. Really don't know why this is not realised already. I also requested this a long time ago. Still waiting...

+1 !
Including popup dialog with new message
