Hi, I propose to add few ConvertSelection options (replace is tedious to use):

1) Trim of whitespace-chars (below 33 ASCII code) at the ending of selected lines.
"Here_is_a_line.____" becomes "Here_is_a_line." (_ is a whitespace)

2) Elemination of duplicated whitespace-chars of lines.
"_Here_is___a_line." becomes "_Here_is_a_line."

3) Elimination of linebreaks in files like 80-columns limited text files to transform them to plain text.
"Here is a long paragraph
broken in column-limited
file.
2nd paragraph..."
becomes
"Here is a long paragraph broken in column-limited file.
2nd paragraph..."

4) Transformation, opposite to #3. When selection is transformed into N-columns wide text.
"Here is a long paragraph broken in column-limited file.
2nd paragraph..."
becomes
"Here is a long paragraph
broken in column-limited
file.
2nd paragraph..."

Thanks
