FORMATTING TEXT - READABILITY ISSUE
No longer possible to apply more than one "special format" (Bold, Underline, Strikethrough, Italics) to a continuous string of characters.
This is a real pain in the arse. Combining formatting was extremely useful when posting blocks of text where different sections/words/phrases could be "highlighted" differently.
It is much more difficult now to avoid misunderstandings and reduces readability. "Workarounds" are long-winded and take up time and space, eg. posting a block of text followed by extracts that could previously have been highlighted (or struck out) in-line within the text.
BRING BACK ADVANCED SEARCH
Search is now USELESS.
Echoing what prh47bridge said above re Windows PC (I am using a Mac):
As others have said, the current search functionality is worse than useless. Yes, it is quick, but that doesn't help when it can't find things. For example, if you search for posts I have made mentioning the word "admission", it produces just two results. A similar search using the word "appeal" also produces just two results. Given that I have made thousands of posts mentioning these words, this is ridiculous. Many other searches using keywords from my past posts fail to produce any results at all. I currently have to use Google to find any of my past posts to which I want to refer.
I could give my own examples demonstrating the same issue.
ACCESSIBILITY IS WORSE
Echoing previous posters above. Absolutely shocking. One of the pleasures of using Mumsnet previously was how accessible the site was.
I was always worried by complaints from members that Mumsnet "looked old fashioned" and that at some point those complaints, from members who clearly know bugger all about accessibility, would be heeded.
The particular way that Mumsnet used to "look old fashioned" was a positive accessibility feature.
