I agree with many in that its feature set seems very small compared to its chrome/firefox sibling, but this is something else. I think settings can include at least few more info like version numbers, current ie(windows and ie version, etc.), last date abp automatically checked for update, state of last filter update(like last update date and its success/failure state), etc.
I don't think they are very much of features; it's rather few more logging and proper display to users to help understand how abp has been acting under cover.
I hope at least some of these changes make to the next release!
