Resizable progress edit-box or list-box

One more desire: when synchronizing/backuping etc., there is a resizable window informing about process of copying files. When I resize it, the internal control (edit-box? list-box? rich-edit?) stays unchanged. So when copying a file whose path is too long, it's necessary to scroll.

Would it be able to make the internal control resizable and to save/restore its size between application sessions?

Thanks
