I believe I have provided a fairly comprehensive list of requirements, so that a best answer would be possible. Of the 10 requirements I've noted, only 2 could be considered subjective (History of privacy-consciousness and inoffensive interface).
Along with what @random has to say, it is worth nothing that what we consider acceptable has changed over the past few years. What you gave us is dated back to 2010, when it was fine. That was 2 years ago. We no longer accept such questions as being on topic.
You are very welcome to ask us for help and shopping questions in the Chat. Our room is Root Access.
It isn't any worse, but now that you've found one that has slipped through the cracks, that too has been closed.
These "I have a list of specs, fill my hole of desire" type questions beg for a list or for everyone to throw in a suggestion of what might fit.
They are, without a price tag, shopping questions.
It is better for you and others in future to just try something and then see where it comes up short. Then, ask the community for help in getting the product to do what you think it may be failing on. If they so then happen to suggest another program entirely, so be it.
