Adding a container to the left of the Activities view

[rastersoft <raster rastersoft com>]

Hi all:

I'm working on an extension and I want to add some elements at the left
on the Activities view, in the same place where the dash is.

I tried with Main.overview._overview.add_actor, but it adds it at the
bottom.

How can I do that?

Thanks.
