Instead of complaining what it doesnt have, suggest what you want to have. You seem like a grumpy person from what iv read, and if youve found some bad points about paint.net, help us help you, ask about other ways to get what you are trying to do, and suggest easier options. If your so desperate to have an option no-one seems neccesary, see if a plugin dev would be willing to help you, or code one yourself. Im sure that many of your problems can be solved quite easily. Just needs a little thought.
And dont have a go at the dev or admins like that. They try to make PDN better and its forums better, and they are doing a good job. They dont want to be rewarded with this. theyd much rather moderate your ideas and suggestions, taking note of whats good and giving constuctive critisism instead of sorting out rants like this.
