AO3 Enhancement Suite is a browser extension that aims to improve upon the already great experience on AO3 by adding various additional features. New features currently include: - Autosaving Comments: Comments will autosave on a per-work basis as you type so you don't lose them if your browser crashes or you close the tab. - Floating Comment Box: A floating comment box that follows you as you scroll with customizable opacity. - Hidden Authors & Works: Hide works based on their author, fandoms, amount of fandoms (crossovers), archive warnings, relationships, characters and additional tags. - Insert Selected Button for the Comment Box: Insert your selected text with customizable formatting. - Search Presets: Save and reload search parameter presets to quickly find works that suit your tastes now and in the future. - Tag Collapse: Hide excessive tags on works with a customizable threshold. - Additional Work Stats: New "Average words per chapter" and "Estimated reading time" stats on works. All features can be enabled or disabled and some have further customization options!
