Suggestions for extensions to be integrated

Should be merged

 * Assert Edit [disablable]
 * CategoryTree — may be included as optional configuration variable [disablable]
 * CharInsert — thought he was admin it was in core :)
 * DeletedContributions — looks like essential, why wasn't it implemented in the core?
 * DismissableSiteNotice [disablable]
 * ImageMap — useful [disablable]
 * Inputbox [disablable]
 * LinkSearch — very useful – r40830
 * Newuserlog — but there should be ability to disable it for wikis like Wikia [disablable] – r40769
 * Nuke — isn't installed on all Wikimedia wikis, but is handy for non-Wikimedia users [disablable]
 * ParserFunctions — required for Wikimedia-compatibility [disablable]
 * Poem — no disadvantages
 * UniversalEditButton [disablable]

Maybe

 * AntiSpoof
 * BackAndForth [disabled by default]
 * Cite — still have some breakages and not properly handled by clauses
 * ConfirmEdit
 * Configure [disablable]
 * Duplicator - "copy" function available on most systems since the beginning of time
 * Gadgets
 * Interwiki (at least the option to view available interwikis, see also InterwikiList)
 * Maintenance [disablable]
 * Renameuser
 * SpamBlacklist
 * Tab0 (very simple usability helper)
 * Title Blacklist
 * TitleKey
 * Username Blacklist

Should not be merged

 * CentralAuth — not includable
 * CrossNamespaceLinks — even now it is useless
 * ExpandTemplates — doubtable usefulness for usual user
 * Oversight — to be deprecated by rev_deleted
 * EasyTimeline — while it is in Perl
 * BoardVote — Wikimedia-specific
 * FixedImage — Wikimedia-specific
 * SiteMatrix — Wikimedia-specific
 * SyntaxHighlight GeSHi — external dependency
