the entire forum appears chaotic and disorganized.
everything is gigantic and take much more space than before.
Is that on iOS? Everything is the same size here (more or less) on Firefox, but then I can resize the screen with a mouse button press in Firefox.
The biggest problems I see:
* Alerts for posts or quotes to messages no longer appear to have a link on them to go to that new message to look at it. As far as I can tell I have to go to watched threads. But that might be due to the next issue.
* Many "buttons" are not the least bit obvious to be buttons (e.g. view to newest thread in a post is a blue circle, but it does not give the slightest visual indication you can click on it by its shape/design; I gather this is an issue in Yosemite as well and a good reason why skeuomorphic, like it or not has its place in GUI designs as buttons were almost always obvious with them as they LOOKED like something you could press).
* The messages themselves need a light grey background like before (too white now and same as overall background where it was grey/white before).
* The new avatars are huge (limits on size before do not scale well to the new ones after the upgrade).
* Many very old watched threads showed up as new after the update here (but that goes away when you view them briefly).
* Quick replies appear at the bottom of the screen instead of at the bottom of the message you're replying to (probably makes little difference in practice though since posting brings you to the end of the thread anyway so I use a middle mouse click in Firefox to respond so it opens to a new tab instead, preserving where I was reading in the thread on the previous tab).
