Ability to modify signature

Hello

I have a signature with many details, for usual mails to third parties. When I discuss with other people, I often want to remove some details.
I could do it with some keys combinations until NC 21 at least. Since 1.13.4 at least, the signature is read-only and I can’t remove it, totally or partially.

bug or feature ?
