Regarding point 2, I use this code assigned to a menu:

--delete all trailing blanks chars
function trim_trailing_spaces()
   local buffer = buffer
   local n=0
   for line = 0, buffer.line_count - 1 do
     local trail = buffer:get_line(line):match('^.-(%s-)[\n\r]*$')
     if trail and trail ~= '' then
       local e = buffer.line_end_position[line]
       local s = e - string.len(trail)
       buffer:set_target_range(s, e)
   if n > 0 then
     ui.statusbar_text= 'Trimmed lines: '..n
     ui.statusbar_text= 'No trailing spaces found'
