[imp] Editable from: field

[Jean-Luc Wasmer]

Hi,

I upgraded IMP to 3.2.1 and horde to 2.2.1

Unfortunately, the field to enter an e-mail address _by hand_ in the
composition window is not there anymore!
I can only choose a predefined identity.

Is there a configuration option to enable in order to have the editable
"From:" field?

That would be upsetting if this feature has been removed, since IMP was the
only e-mail client I found that allowed this.
