Problem Statement

Please, allow us to hide, or even better, disable the pinned message in the vs code extension. As you can see in the image bellow, sometimes i bearally have space to read what claude said before the AskUserQuestion modal, this is quite annoying... I really dont care about my last message, its just space that is lost for me...
