Should be doable -- though maybe not quite as nice as the standard UI,  
because there's (currently) no way to autoresize the window to conform  
to the text size. Create a nib with an NSPanel; set the Custom  
Subclass of the window to the borderless subclass already present in  
TM. Add an NSTextView (graphics/fonts disabled) for the completion  
text and an NSTableView for the suggested completions; for the  
NSTextField value binding, set the 'Continously updates value' check  
box. The main loop would look something like:

	dialog.wait_for_input do | input |
		user_text = input['completionText']
		suggestions = completions_for(user_text)
		
		# Subword completion
		if user_text.end_with?(TabKeyChar) then
			user_text = common_prefix_of_strings(suggestions) || user_text.sub(/ 
#{TabKeyChar}$/, '')
		end

		dialog.parameters = {'completionText' => user_text;  
'suggestedCompletions' => suggestions}
	end
