[Bf-python] How to change a *VectorProperty size?

[Goncalo Morgado]

I see.
What would be the right path to visualise the CollectionProperty items in a
panel? It is my understanding that adding a layout.prop() pointing to the
CollectionProperty will only show the number of items, but not the actual
values.

Thanks again,
Gonçalo
