when searching trough posts ( e621.net/posts?tags=[tags] ) on desktop, there is a button on the right that toggles "fullscreen mode", this hides the tags sidebar, similar to how the UI is on mobile

it would be nice to have a similar button on the post page ( e621.net/posts/####### ) to change the ui such that the sidebar doesn't show up on the side of the image. then the image would be centered on the screen, and if you set the Image Width setting to "Fit (Horizontal)" the image would nicely basically touch both sides of the window
