Though, actually, when I looked on my iPhone, none of them were purple, not even the ones I knew I'd looked at on the phone, until I opened it again, then it went purple. I assumed that was a Safari/iPhone thing, rather than a MN thing.
Threads I'm On looks crap for me too, it is hard to read as it's all the same colour and links don't turn purple once I've clicked - which is how I would know where I was up to in reading a thread, IYSWIM?
Active Convos is OK for most people (anyone got a problem with Active Convos?)
But Threads I'm On is not going changing colour.
Is that right?
By the way, BigTech told me last time I poked my head in the Shed about this that a thread in Threads I'm On will only change colour if you've posted on it. If it's a thread you STARTED but haven't posted on since, the colour doesn't change.
Because then you know where you've read up to - so if I look at this thread in 'threads I'm on' and click on a link to a post - say yours, Helen - and when I check later there are more replies I can jump straight to the next unread one, raqther than have to scroll to find where I was reading up to. does that make sense?
NB it's not the thread titles in Threads I'm On we want to change colour (because, as you so wisely point out , we know we're on them!) - it's the posts we've clicked on which need to change colour, so we know where we were up to (which is just another way of saying what PrincessT said, but more explicitly)(I hope)
