1. Snippet Manager: Okay, this was apparently user error. I forgot that the file name means nothing in a snippet. It's the description in File Properties. It feels rather convoluted, but that's okay.

2. ZedGraph: If I make a major change to a worksheet above the graph, it frequently loses the line width and reverts back to the default of 1.

3. If I select a closed area and try to slightly shift it, SMATH inserts significant space above the top of the worksheet. I have to use the delete button to get rid of that space. Unlike other items in a worksheet, if I want to slightly move a closed area, I have to successively use the delete and enter keys on my computer.

SMATH indicates I have the most recent update. See figure.
