For me, and for many people with depression and schizophrenia, all change is difficult.  I think your changes are an improvement, although it will take me some time to get acclimated.

I think your "search" function could be approved.  Because I have even "searched" for the exact title of a sharepost and not been able to find it.  I have not found any logic to the way search results are organized.

I've given the new format almost a month and still have difficulties finding the wonderful articles I frequently reference on the Migraine site.  I find the new format to be very frustrating and tough to navigate.  Although the search feature has improved somewhat over the years, it still does not allow me to narrow in on the articles I am looking for now that I find it harder to navigate to them.  The last issue I have is the constant popup on the bottom of the screen for the Check a symptom.  I know where to go for that, but the popup makes my small screen even smaller.  I can hide it, but it reappears when I go to the next page in an article or another screen.  I would at least like to hide this popup for the duration of my session.
