In that case: It takes 1-2 weeks to realize it is actually better...
There are things that are better and things that are worse
I personally think the 3.8 interface was more ergonomic, offering more info for less clicks
Sure, for some that may mean Clutter. And trying to organize the clutter usually means a more compartmented/nested layout which mean less info for more clicks
I still hate the fact that in both galmap and sysmap the system/body information was split in two, requiring extra mouse movement and extra clicks.
Having the bookmarks organized/filtered can be a nice thing, but i still miss a global view for all my bookmarks
Having some big tiled buttons for bookmarks is a lot of screen estate wasted.
Same for Outfitting modules, having them filtered/categorized is a good thing - until you realize that you have no mean (except to browse through all categories) to find out if you have all your modules onboard your carrier or you have some forgotten in some stations.
So, yea - it could have been way nicer than 3.8, but it isnt.
