minor gripe: the “New” label color is inconsistent between mobile and desktop
Mobile
Desktop
The activity page of a user look like this:
And landscape
Some topic titles are even shorter. And aligned more left by a few tabs.
Galaxy S10, Chrome, Mobile view (the Desktop view looks even more funky…)
I still feel lost when I land on the latest topics page.
What do you mean exactly?
The issue with activity feed and some other alignment related items are all fixed now.
Issue with double line on the header is fixed now.
There is a Discourse Math plugin that was taking over. $5 should display properly now.
Sorry for the delayed response… this is just my preference and it may not be what others are used to. I preferred the previous compact layout of the Latest topics page. When you load the latest topics page, there’s little need to scroll down to see if any topics interest me. At one glance if nothing piques my interest, I move on. Is there an option on the end user side to not display these, it just takes too much screen space 
I don’t have a screenshot of what the previous landing page looked like but it just seems there’s just more ‘eye travel’ required on this new layout. That or my eyes are getting lazier.
I’m finding it harder to distinguish between New topics and topics i’ve read.
1, What @eibyer said, this is unnecessary…
It also takes up too much space.
2, These topic groups are ineligible anyway, because you have the grey back ground too dark, it clashes with the black text and is uneasy on the eye, as if it needs to be said it disobeys all modern webpage construction etiquette…
For each set of text within your app, the color contrast – or difference in perceived brightness between the color of the text and the color of the background behind the text – is recommended to be above a specific threshold. The exact threshold depends on the text’s font size and whether the text appears in bold:
The following image shows two examples of text-to-background color contrast:
Figure 1. Lower than recommended (left) and sufficient (right) color contrast.
3, The grey and white zebra patterns are distracting and make reading a less enjoyable experience.
4, I’ll mention it anyway even though @yenyr you seem to have your heart set on it, I don’t like the new trendy grey thin text size you’ve chosen for the forum, I prefer what we had before, black and regular text size, there’s a reason the WebCoRE, Sharptools, Hubitat all use it, it’s better.
Topics you have visited will be purple. Individual posts you haven’t read have a blue dot to the right of them.
The purple isn’t very obvious. I forget what the colors were before (light blue?) but it was much more obvious. The new flag being grey doesn’t help either.
Hmm the dark grey text on light grey background is playing tricks with our eyes. The purple on this stands out because of the other color underneath it.
We have some changes coming that should fix the readability.
By default visited used to be light grey. Much like the meta discourse.
I actually think the purple is more obvious than it used to be.
Although the visual isn’t as important to me, my understanding from UI design is that in a community forum you don’t want the “visited“ to be more obvious than the “not yet visited” topics. You want them to slightly fade into the background, so that the eye can scan all the way down to the bottom of the page and the “not yet visited“ topics will be the ones that stand out. That’s why in the default color scheme the “visited” topics are gray.
Making them purple means that they are demanding more attention from the brain than the ones that are “not yet visited,“ which I believe is the opposite of what most people expect in a forum.
Note that, as always, context matters. In a list of search results, such as Google, bright purple is a helpful color for visited links because people are often looking to go back to something that they found before. And of course the not yet visited links are in bright blue, which always demands attention. But in a forum like this one, people are most often looking for new content. they don’t need to revisit something they’ve already read unless there have been new posts added.
And the problem is made worse by the fact that the “not yet visited” links in this forum are black, not blue.
Or at least that’s how it was explained to me. 
Minor update -
Darker text in category tags
Smaller padding around category tag text
LOL I think I will be the only one who liked the previous look better
my eyes are straining from the new settings.
Do you mean the old theme or the previous lighter text?
