1.) This will be the behavior for the pencil tool from version 0.7.10 forward.
For other tools, I'm still thinking they are more of the type "draw one object then move it around" so I'd rather have them fall to the "move" tool right after they are drawn or at least when we change frame...
(Subject to refinement if everyone think it should behave differently.)
2.) When you use the "Save" menu, it will be working on the currently active video. This is the one that has the blue border around the frame. You should be able to save one set of data, then select the other video and save again.
If you save the data file (.kva) with the same name as the video and in the same folder, it will be loaded automatically with the video.
Hope that helps...
