Moving staff and strange bug

It is clear that Notion 3 is a work in progress. There are many features that are still missing with compared to Sibelius, however, it is also clear that the Notion 3 team has a brilliant new way of addressing things that make this app fell much more fluid and the user experience is over all enjoyable. It feels like writing music on paper, and that's what I was looking for.
Now onto my question and my complaint
1) I can not figure out how to manually move staffs in order to change spacing between them, to accommodate extra ledger lines or articulations. I know how to re-order the staffs, but not how to change the spacing.
Now a bug:
After working for a while on Notion SLE (with VSL) I left it running for about 1 hour while I was doing other things on my other computer. Eventually it just crashed. I tried this again and it kept happening ! any ideas, or anyone else experienced this?
I look forward to the day when I can abandon Sibelius completely, that day feels close, but not just yet. For now I use Notion as the main tool, then bring in scores into sibelius for touch up.
cheers and thanks for the great product and your amazing supportive attitudes.
