Initial width and height of a docker panel

[shashi-drishya]

Hi @mathuo,

I am wondering if there is currently a feature that allows specifying the initial size of a panel, where both the height and width can be defined during setup.

I believe this is probably something similar to #590

i.e. when it is possible (since it's not always possible to use an exact height and width) use a user-defined preferred height and width

Let me know if that makes sense?

Tracking in #640
