I've mentioned this on each upgrade since 3.62. When I start to type in an address, in all versions of TB up till 3.62, the first letter would trigger the autofill. Since then, it is at least 2 letters to start autofill. I am very used to filling in 1 letter and having autofill do it's job. I have been unwilling/unable to retrain myself to use 2 letters. I know this sounds like a quibble, but it is important to me. Any chance we can get it back to autofill starts on first character, or at least be able to set that as an option?
