Bulleted lists are unstable under Cut-and-Paste and Undo ope

Bulleted lists are unstable under Cut-and-Paste and Undo operations and they are incompatible with Cut-and-Paste from/to MS Word, Wordpad, etc.

Here’s how to reproduce the first problem:
Start a bullet list in the Scrivener Editor.
First bullet (solid), appears in far left margin.
Hit tab, next level (circle) is indented to first tab stop.
Hit shift+tab, primary level (solid) bullet now indented halfway to first tab stop
Now, copy and paste a few bulleted lines. Indentations shift around.
Next, ctrl-Z undo a couple of times. Bullets, levels and indention all get all screwed up.
[Nice to have: Select several lines and hit Tab should increase indent instead of erase]

Here’s how to reproduce the second problem:

Cut-and-Paste a bulleted list from MS Word or Wordpad
The first level bullet characters are not proper.

Cut-and-Paste a bulleted list from Scrivener to MS Word or Wordpad
All the indentation levels are collapsed to first-level.
