The Pencil Project is a tool made for proto-typing and for that I would need a feature of reusable components. For instance, when creating a header component I want to re-use it several times in the same document and have the changes I make to that component propagate to everywhere it is used.
The workaround I use now is to update the header in place and the copy those changes to all the other places where the header is being used which is a slow and error-prone process.
I did not find such feature in Pencil. Does it have such a feature?
