"Expand meta node" feature request

Dear KNIMErs,

Quite often, "Expand meta node" creates undesired overlap with the rest of the workflow. In order to fix this after the expansion has taken place, it'd be nice to have the newly-expanded set of nodes selected for simplified rearragenment (Ctrl-clicking a bunch of nodes in crowded space is rather inconvenient).

Thanks for considering it.

Cheers
E
