The team has fixed a great many of Violitions mistakes in FS2. One area neglected, however, is the UI.
As it stands the UI is clumsy, ineffiencent, isn't designed for the resolution we use, isn't designed for the 3d models we use instead of icons, and has huge swathes of dead space along with infomation and buttons crammed into corners.
Specifically talking about the 'ship select' screen, the 'ship data' element is far too large, and 30% empty. The 'ship preview' window is far too large. The 'ship inventory' section is too small, doesn't show enough different ships, and doesn't 'page' through availible ships. It also doesn't have a scrollbar. The 'wing' area is okay, but could be make larger and clearer by reducing the massive waste in the centre of the screen.
The 'loadout' screen isn't so bad, but still suffers form 'Violition clicky syndrome'. Slightly narrowing the gun and missile images allows almost twice as many in the same area: reducing the deadspace in the middle could allow almost 3 times.
A good UI doesn't force you to click 'next ship' five times to find the one you want. It doesn't have massive, almost empty windows - like the 'ship data' one - on the same screen as squashed working elements like the 'ship inventory'. Looking at the ship select screen from a USER perspective, the text and model are simply fluff and almost irrelevant. The fact that those two elements crush the USEFUL section, the ship inv/wing section, into the bottom third of the screen is terrible. Simply removing the empty parts of the preview and ship data windows would allow far more ship selection data and functionality to be displayed - which is after all what the screen is for. THis would have no negative effect on the 'eye candy' nature of the ship preview.
The loadout screen should, in my opinion, drop the 'class 1 - 8' rubbish and make a proper linear scale based on ACTUAL damages. The current classes don't properly reflect the differences in damages vs shield, hull and sub. Of course, they don't tell you damage vs sub at ALL.
Personally, I'd implement ship and weapon tooltips that give important stats (like speed, shield, armour etc or various damage stats) to streamline usage. Its a copout design-wise to say 'but everyone already knows'. Everyone has learnt to use this horrible UI, but that doesn't mean it shouldn't be fixed. Everyone liked the old Herc model too.
