This is really low priority, more a cosmetic quality of life thing which won't affect too many people I wouldn't think.
I do a lot of Vault Server installations, and in the world of virtualisation a lot of Vault servers are now VM based which you tend to access over remote desktop.
Also, some installations are done over VPN, over slow/poor connections. Personally I find RDP is perfectly workable, until the wonderfully colourful snazzy data rich installation dialog box appears with it's ever changing artistic quirky background images. These images cause chaos over slow lines whilst RDP is in session, I'm sitting right now watching my RDP session connecting from Aus to the UK flicker and jerk as it tries to render and capture the flowing colourful images being sent by the Vault Server installation wizard, I can't select anything until it's rendered each frame which is ever changing. It's so much of a bottleneck that I have to minimise the dialog whilst it installs.
Please consider removing these silly pictures from the Vault Server installation process, they're not required for a server side install. Please make the dialogs basic and not so visually loaded, or at least give me the option to launch it without them.
Cheers, Neil.
