Your suggestion IS a great idea! and something I would like implemented too. 🙂
I belong to many forums and I have interacted with many developers in the past, timo is the most responsive and helpful developers I have had the pleasure of dealing with. He considers all and any feature request and improvements which we all throw at him by the thousands! As you can imagine, many people don't bother to search a topic before asking for help (I'm guilty of this too!) timo must get so frustrated with having to constantly remind people to check if there is an existing discussion with the same request.
I have never known (since being a member of this forum and reading daily) timo to be rude, impolite or arrogant. He is a decent developer who is REALLY responsive and cares for his software in a big way. looking at your interaction I do not deem his answer arrogant. He was merely pointing out that there are four other requests just like yours. That's not to say that he thinks your idea is bad or anything.
I hope you didn't mind me giving you my opinion, it's not an attack on you it's just conversation 🙂
