This page layout was fine as it was and now you have changed it again. It was ok this morning, yesterday and the day before. Now it has changed again. I was using Mozilla with 200% zoom which meant that the maion central threrad showed perfectly in the centre of my TFT screen. Now the end bits are cut off again and I am having to use the slider bar to see the end bits of the main thread. Why did you not leave well alone?
Reduce the zoom for Pete' sake. We've all been saying that the new layout was too narrow down the middle. They're listening and getting it right to preserve our poor mice's (?) scroll wheels. You can't please everyone!
Don't agree with your comments so far. I happen to like just reading the central thread and I prefer this to be in a font size I can tread without squinting at. I DO NOT care about the side panels. Many elderly persons prefer large text - I take my specs off to read and for once - only once - this site was perfectly set up. Many agreed with the new layout. You too may agree when you get a little older!
You have hit the nail on the head. Many of your forum readers are old. In my case approaching 70. The narrow central thread could be expanded to just leave the central thread filling the screen with large text on the Mozilla browser. This was ideal. Now you have changed it again I (and no doubt several others who had adjusted to this site) will now have to use the slider bar again with large text sizes. You are pandering to the younger element again.
As Taran says, the site is now looking better than ever and I think it would take some extremely hard work to improve the layout.
Nothing is ever 100% to all people, but this forum is now very close. As I mentioned above, reduce your browser settings back to normal and give it a day or two for you to adjust. I think you will like it too.
