Weight painting in Grease Pencil, Issues

Grease Pencil weight painting with armature is not yet optimal. One can not yet Cntr Select or Shift Select a bone to test weight painting results. In weight paint mode the object becomes “disconnected” from the armature pose. (see attachments). It would also be nice if there would be a weight smoothing brush.
Is in the pipeline to make it work like in the 3D mode? That would be awesome!
