Recent changes were made to benefit those using SL Marketplace with mobile phones in portrait mode. But Second Life is still largely used by a majority of desktop computer users and the SL Marketplace should mirror that too.
The recent changes have negatively affected the way SL Marketplace now appears on desktop computer screens, with two-thirds of a desktop screen now having wide empty side borders which are left unused and wasted.
Please introduce a Desktop Screen Mode option to SL Marketplace, allowing the entire width of a desktop monitor screen to be utilised, with a wide variety of screen size options too, just as the SL Viewer already has.
Attached are images of how SL Marketplace currently appears on a Desktop PC Windows 11 (16:9 screen, 1920x1080) and how I would improve SL Marketplace's UI to allow the full width of a screen to be utilised, with a "Screen Size" option button added.
