If you use "Recent posts" you get a clear delimiter for only the new posts since your last visit. That could perhaps be a good indicator for you as a mobile user to easily see what new posts there are since the last time you logged in?
You can also use filters (top right above the first thread on the "Recent posts" page) and filter out read posts etc to make the list more compact and easy to overview.
If you use the filter "only unread" in combination with that you manually "mark the forum as read" you will get a very compact list of only the new and unread threads!
Just an idea!
Suggestion: The new set of smileys are fine and of a more "current" type so no complaints there. They are however too big because they ruin the formatting of the text because they are almost three times taller than the standard font, hence why it ruins the formatting.
Do you have a set of smaller sized smileys of the same set? It would make it easier to read and make it easier to use them when writing - especially when writing longer texts in paragraphs and you don't want the spacing to break just because you use a couple of smileys...
I've got a black belt in using pictograms due to my kids being autistic and smileys are as effective when you want to deliver a "feeling" to what you're writing, or perhaps clarifying a joke or that you like something, hence why I take the usage of smileys seriously - at the same time with a ;) or a :p
Perhaps I'm the only one thinking this deep about smileys, then you can ignore my request, but if you agree but only have the set of smileys in one size then I can source, and send, a new set of standard smileys for you in the correct size.
