The effect is subtle², since I'm a bit color blind, but I'm pretty sure one just needs to adjust the CSS settings⁴ for "visited" (?) to change colors or other attributes.

Dunno the right CSS code for that, but other monks and search engines might help.¹

Disclaimer: this won't help if you use multiple browsers tho.³

²) and probably watered down by color settings for different creation dates.

³) and you'll have to open each post individually for them to be "visited"

⁴) in Display Settings or RAT Style Settings . Additionally Newest Nodes Settings might be of interest too.

"and already visited links have at least another color"

Yeah, that's what I've been using. I just click any read node directly to mark it as visited. I guess one setting that would be nice for both Newest Nodes and Recent Threads would be the ability say "I've checked all older than [x] days old" instead of simply "I've checked all of these". I realize you can "Clear my 'last checked' time" and simply set 'Show nodes created within the past x days', but then you lose the td.reply-new css styling functionality.

OK, I see what you mean now.

I don't know if the gods would approve that and I learned not to invest in patches which will not be accepted.

But you can hack that for yourself.

If you right-click on [I've checked all of these] you'll be offered to investigate the button in the dev-console.

There you'll find a timestamp in pageloadtime which can be manipulated

<form method="post" action="?" enctype="multipart/form-data">
<span><input type="hidden" name="node_id" value="3628"></span>
<input type="hidden" name="pageloadtime" value="1709739362">
<input type="submit" name="viewedNewNodes" value="I've checked all of 
+these">
</form>
[download]

after substracting 86400*days I filled the new value in and hit the button.

To make it more comfortable, you can either write a bookmarklet with javascript: protocol or a nodelet-hack to do so.

HTH! :)

Not sure what you mean...

Maybe try "minimal" view on RAT, to combine the benefits of both worlds

Minimal

This node just shows the sample set just like Newest Nodes would but with notes grouped into their sections and possibly threaded.
