Filtered tags, Hide filtered tags completely, and Preview filtered tags all allow visitors to control the visibility of unwanted content

when Hide filtered tags completely is unchecked, files with a visitor's filtered tags will still be returned in searches but their thumbnails will be covered with a warning triangle

when Preview filtered tags is checked, hovering over thumbnails of filtered files will remove the warning triangle allowing visitors to see the actual thumbnail

when Hide filtered tags completely is checked, files with a visitor's filtered tags will always be omitted from search results (without having to manually add their tag negations every time)

when Jumbo thumbnails is checked, the size of thumbnails is increased

Uncropped thumbnails controls whether the entire thumbnail for each file is made visible, or cropped by scaling them until they fill their entire square in the search results grid

Fit files vertically controls whether images on the view page will be scaled to fit the entire image in the window or not

Unblur R-18 controls whether thumbnails of files tagged with #r18 will be displayed the same as other thumbnails (but with a small R-18 indicator), or are blurred and must be hovered to preview them
