Go to first unread topic in block feeds

[FZ]

My members hate the new Invision 4 compared to the way I had my site running with 3.4. It's cost me a lot of traffic. People simply don't like the interface and I can't say I disagree with them.  

One of the problem areas is that under 3.4 I created custom blocks where I specifically included the parameter to go to the first unread post of a topic in that feed. The new system doesn't appear to do this - when I create a block for a feed clicking on the results always takes the user to the first post, regardless of whether they have read it or not.

In 3.4 I could understand the syntax of the code to be able to fix this, but now I am lost and to be honest, I don't know if I want to expend the effort in learning whatever the new way of coding things is (because you will probably just change it again at the next major release).
