Oh you do like to waffle to hide the facts! To answer my question doesn't need a review of the software available, or your opinion on what constitutes professional!
Let's try some simple yes or no questions, if you would be so kind...
1) Does software exist that uses numbers to indicate tone?
2) If you don't have software that allows you to use tonal indicators, can you use numbers to show tone?
3) Did you start this whole thread to shame Somebody when he never said anything about numbers/pinyin in the first place?
4) Don't you think you owe Somebody an apology?
