• Go multi-user (one data file per user ; when not logged in, you see all public links of all users).
• Go multi-user:
  • One data file (Not one data file per user)
  • Entries can be:
    • Public : Anyone can see them.
    • Shared : Only logged-in users can see them.
    • Private : Only the user who created them can see them.
• Encrypt private links (this will protect private links even if the data file is stolen). Client-side javascript encryption (with sjcl) or server-side ?
• Other export/import options ? (CSV, RDF, single HTML file… ?)
• Push updates to client ? (auto-updating html page)
• Automatic backups (every week ?) (how ? Copy file under a name with date ? email ?) * Prepare source for translation.
• Sniff browser locale/language ($_SERVER['HTTP_ACCEPT_LANGUAGE']):
  • automatically choose corresponding translation if available.
  • automatically format date. done (Note: some servers do not have locales like "fr_FR" installed… this includes mine )

• Show new links since last visit ? (maybe using a cookie which records the linkdate of the latest news ?)

• Add automatic description by reading meta headers (patch by Yohann Nizon)
• Support Firefox json export (because Firefox HTML export does not export tags (!)).
• When editing a link, add a button "Save as new" which would change the date of the link, effectively posting it as a new link (This can be helpful when you want to push an update on an existing link).
• Allow date editing of a link (Warning: this would break its permalink).
• In config, add an option to make the Shaarli private: The Shaarli will not show any link, except if you are logged in. (This can also be used to temporarly "close" a shaarli).
• Think about adding auto-twitt of links (see this)
• Make Shaarli HTML/CSS code W3C compliant (apply idleman patch)
• Allow configuration of QRCode generation URL in config screens.
• Add better navigation in the "Daily" page (calendar ?)
• Allow spaces in tags.
• Find a way, when you find an interesting entry on another shaarli, to import easily the entry in your shaarli (adding a "via" in description pointing to the permalink of the original entry).
• Defer javascript execution to speedup page display (as javascript is not used to build pages).
• Write proper user manual, in a separate wiki page (installation, bookmarklet usage, keyboard speed-up tips, how to use Shaarli as a pastebin/online notepad, who to use Shaarli as twitter, how to customize Shaarli (colors, logo, templates…), backup/restore, how to filter picture wall or RSS/ATOM feed by tag or text search…)
• Add statistics ? (database size, number of links (private/public), free space on webspace) (No access statistics)
• Add website favicons ? (They would have to be cached locally to avoir request to those website everytime someone reads a Shaarli page ; That would be bad for privacy.)

  • Extract data (search by tag, full text), in json format.
  • Others ?
• Allow 1-click Shaarli upgrade in admin interface.
• Correct tag encoding in tag cloud.
• Try to support description attribute in Scuttle exports.
• Add weekly and monthly pages like the daily page.
• In the default database (the 2 links created when you start a new Shaarli), use ZeroBin instead of Pastebin.
• When using the bookmarklet button on a blank page (eg. about:blank), create a self-pointing entry (like "Add link" > Enter).
• When using the bookmarklet and the login fails in the popup window, properly redirect to the initial &post=… URL.
• After adding/editing a link, go back to the same page and scroll to the item which has been edited (using an anchor). done.
• Add a "Report a problem with this link" ? (so that users can report a 404, for example).
• Archive a copy of the link (page, image…) ?
• Website screenshot ?
• Custom thumbnails ?
• When link points to Shaarli it-self, do not use redirector.
• At installation, make sure sessions are working properly (Lots of hosts do not seem to have a proper session path defined). done.
• At installation, make sure shaarli has the right to create a directory in its installation directory (Some hosts seem to prevent web user to create directories at document root).
• Include Timo's patch for proper charset/encoding detection in page title.
• Re-write shaarli entirely (better object model, and use namespaces to avoid conflicts)
• When sharing a Shaarli permalink, automatically add "Via" (Detect by including RDF metadata in shaarli pages).
• Add DublinCore data ?
• In RSS/ATOM feed, add a parameter in URL in order to choose which URL to put in <link> tag: Permalink or final link. done.
• When using fulltext search, highlight the words in results.
• Put Shaarli on GitHub, damn it ! done !
