Backblaze B2 Userscripts

This userscript adds range selection, modifier-click toggling, and size sorting to the Backblaze B2 file browser.

What it does

• click a checkbox to set the anchor row
• Shift+click selects the range from the anchor to the clicked row, in display order
• Ctrl, Cmd, or Alt+click toggles the clicked row
• version groups are handled through Backblaze's own checkbox handlers, so totals and bulk actions stay correct
• adds a "Size (sort)" button to the Size column header
• the first click sorts loaded files and folders largest first, and each later click reverses the order
• folders keep their version rows, and rows with unknown sizes sort last

Limitations

• sorting and range selection only cover rows already loaded in the page
• depends on Backblaze's current b2-browse-* class names and image file names
