But you do hit the point for removing this "extension" that is no extension at all: you (average user) cannot deactivate in the UI. Being integrated in the Office is as simple as adding a checkbox on the Options dialog, and for system administrators an option in an xcu file. Besides, now as preregistered extensions, they consume space both in the installation folder and every user directory on your system. Integrated into the Office code is simply a library, configuration files are merged, and images part of the global images.zip. Besides, as preregistered extensions, they are broken on Linux. The fact that the Presenter Screen ended as a preregistered extensions is just a hack to workaround bugs, not to mention the whole buggy unopkg sync and preregistered extensions by itself (no wonder Stephan Bergmann removed them long ago http://lists.freedesktop.org/archives/libreoffice/2012-August/036627.html) Besides the fact that, although being linked only to URE libs, this is by no means a "normal" extension, and has deep dependencies in the core code that go beyond mere UNO services as could be used by other extensions; so the fact of this being an extension is no argument in favor of the code being easy to maintain, on the contrary, by looking at the history [ariel@localhost presenter]$ git log --oneline . 1b138b4 i121873 - Integrate the Presenter Screen 7f0e1cf #121388# - adapt renaming: "Apache OpenOffice" --> "OpenOffice" 77d41e6 i119977 - Update version number to 4.0.0 4edadde Fixed build breaker and some cleanup. 8c43b8f #i119206# use generic methods in presenter-console's makefile e35efbe fix extension maximal version dependency b9e592a extensions with updated license get a new version also update min-/max-dependency to Apache OpenOffice 3.4+ 5729e2e #i119168# update granted extensions to match their ALv2 license 9979154 Added AL2 license. c30c02e Update headers to Alv2 headers ffe7841 Update headers to Alv2 headers cbc6f46 remove svn:executable properties from more source files 50c3fa1 remove svn:executable properties from document templates and samples ff38d84 remove svn:executable properties from source files c5fe3be Update headers to Alv2 headers fbb9cd7 Update headers to Alv2 headers 1f83643 Update headers to Alv2 headers 539ae5f Update headers to Alv2 headers 1842c5f Update headers to Alv2 headers c946a2d Update headers to Alv2 headers 00639e4 Update headers to Alv2 headers 6b9fba5 Initial import of the old OOo hg repository tip revision. this shows the code hasn't been touched since it was transfered to the ASF, since 2011: changeset: 276848:2418cfd47c84 user: Andre Fischer<andre.f.fisc...@oracle.com> date: Wed Mar 23 09:42:08 2011 +0100 files: sdext/source/presenter/description.xml description: impress211: #i110990# Increased version number (micro) of presenter screen extension to 1.1.1. changeset: 276845:d8cdb29e0a59 user: Andre Fischer<andre.f.fisc...@oracle.com> date: Fri Mar 11 15:22:17 2011 +0100 files: sd/source/ui/dlg/present.cxx sd/source/ui/slideshow/slideshow.cxx sdext/source/presenter/PresenterScreen.cxx description: impress211: #i110990# Fixed remaining problems with display ids and indices. This could mean: a) the extension is bug-free and full-featured b) it is unmaintained Searching bugs in bugzilla, and looking at the logs in http://opengrok.libreoffice.org/xref/core/sdext/source/presenter/ seems to indicate that is far from (a). IMHO, in the case of this particular extension, having it integrated makes it more easy to debug and hack on, the problem (a serious one in this project) is to attract community contributors to work on it. > Advanced features could be developed as extensions and integrated in > the main code if they meet big success. This is far from reality. Advanced features need integration into the office code. With an hybrid extension that is no real extension because of it dependencies you end up with something difficult to maintain. The Report Builder and MySQL Connector are very good examples, besides the Presenter Screen. Just try to install the MySQL connector and connect to a socket (Unix) or a pipe (Windows); I could cite more examples, but I already wrote too much (besides, I used too much the word "besides").
