I agree. It needs to be more compact where all the relevant information is on one page on my screen. Using a PC, to get to the relevant information that I am interested in, I have to scroll right, left, up and go down-under south of Australia passing the kangaroos and then take a left south-west of Fiji to get to the information I want. It's not practical, fast or efficient way of information gathering.
I agree the old site is too old, antiquated, quaint and needs a revamp, but all the functions and info is at your fingertips. This is not nostalgia for the old site talking.
Personally I am not looking forward to the end-of-life of .org. And normally I love new software and modern looks generally. Hell, I've been waiting for Keepass password manager to update it's UI for years, but in the case of these two subtitle sites, "old is gold" expression couldn't be more true. I get some people don't like change, this isn't about that. Practicality and a lot of hidden functionality is the main reason a lot of users are loyal to OS .org. Otherwise if people just wanted a modern appeal, they would have left OS for more greener pastures years ago to other sites.
I spoke to the new developer (os_dev) several years ago, and he informed me that the original developer who has left the project designed it that way, and I don't think there is much they can do to change that look unless they started the design from scratch. I hope that is not the case any-more, as it does need changing and making it more compact.
Eventually the sites will not run parallel to each other.
Sorry for the negativity. Do wish the best for the project.
