Install the script: https://github.com/evazion/danbooru-ex/raw/stable/dist/danbooru-ex.user.js

To configure the script, go to My Account > Settings > EX Settings, or click the Settings link at the very bottom of the page.

Main features

• Search bar and mode menu available on every page.

• Thumbnail previews: hover over any thumbnail or post #1234 link to popup a large image preview.

• Preview panel: Select Preview from the Mode menu then click a thumbnail. A panel will appear showing you the full post without leaving the page.

• Redesigned tag script mode: Clicking thumbnails selects the post and opens a preview instead of applying tags immediately. After your posts are selected, click Apply or press Shift+A to apply tags. This helps you avoid mistagging posts, lets you select posts in bulk, and lets you see the full image as you work.

• Resizeable tag sidebar: collapse it to get more space, or expand it to read long tags that normally wrap around the tag list.

• Colorized tags in the wiki and in the forum.

• Visible comment scores and extra post info.
