I have recently come across ReText for Linux and use it to write markdown documents. I find it very useful and friendly but would like to see a few more features that would facilitate editing:

• The ability to not only move single lines (Alt-Up/Alt-Dn) but to move an entire block of text. The block would begin with the line the cursor is on and would automatically include all descendants of that line.
• Although it is is possible to use Tab to indent a new line, mapping Shift-Tab to unindent the line would be useful. When more than one line is selected, the entire block should be indented/unindented.
• When adding a new line, the default level/indentation should be the same as the line above. Now a new line automatically starts at the very left.
• I prefer to have a tab between the markdown level marker and the text which to me is cleaner than the single space currently used. Perhaps this could be a setting?

Thank you for your great work!
