- Windows support for open file descriptor with usdcat
- Dark theme support, including sticky user preference
- Deprecated "-dark" flag in favor of "-theme light" or "-theme dark" to temporarily override the sticky user theme preference.
- Indentation improvements
- Do not indent/unindent the ending line in a multi-line selection if the cursor has no selection on the last line. Allow Shift-Tab to unindent the current line when no characters are selected (previously, this shifted the widget focus).
