Responsivity
The new website will adapt to the device you're using. So views and tiles (learned new word!

Some pages, league tables being the main example, will reduce their columns with mobiles or tablets, to only show the more important ones to give you a better display. If you go landscape, you will se more columns appear, on a pc screen instead all columns will be visible.
Custom Position
You can now set a custom position for your players. That position will be then visible on the team selection page where you will have 2 options:
Order by automatic position, will show your list as it has alway been, ordered by the position showed by the players page.
Order by custom position, your list will be ordered by the custom positions you set.
This will come in handy where a player has a tag you don't like, or has no tag at all.
Match Preview
Match preview page is no more displayed with players on the field. It is now a table like those you see in newspapers, this allowed a much quicker page to load, as this page was always very slow in the old display.
Transfer lists
Transfer lists like for sale, free agents, available etc, are now displayed as tiles and not as a table anymore. This should be a better experience with mobiles. Squad page instead hasn't changed due to better understanding.
Stadium page
Has been graphically improved with new images and display
Tactics page
Also tactics page has been improved with more modern images and positions on some tactics as the old ones were very outdated
Manager and club trophy cabinet
Manager and club trophy cabinet, long awaited, are now available in the history page of the manager and club. Please note that not all seasons are already stored. I will ask users to help me with data recovery, carrying on the old project we did in General ITN forum
Manager of the season page
Manager of the season page has now more data. Again, not all yet. I will import all missing data when the new site stuff has settled.
More to be added...
