== Current Process ==
* Dennis added a third tab in the extension manager, using Qt Designer
* extensionsInstallPath() returns platform-specific path to "NA-MIC" folder which has "Extensions-2456" subfolders for all installed Slicer versions
** on Linux, that's in ~/.config/NA-MIC
** on Windows, in AppData/Roaming
** on OS X, seems to be a subdirectory of the application bundle
* Dennis' idea: look for all Extensions-* subfolders – how to do that on OS X properly?
** just found [Extensions]/InstallPath setting in .ini files -> by parsing all ini files, that could work cross-platform
** on OS X, the inis are in ~/.config//www.na-mic.org
* Dennis' plan was to use Python scripting, but using C++/Qt would also be a good option

== Proposed Changes ==
* a new (third) tab in the extension manager, which should list all previously installed extensions
* view should have columns:
** extension name
** Slicer revisions / last revision in which the extension was installed
** checkbox for batch installation, pre-checked from latest previous Slicer revision
** rows with installed extensions could be grayed out
* below that, a button for installing the checked extensions

== Progress ==

* Extract list of extensions installed. Look at npm for the format. '''ToBeDone'''
* Extension manager:
** Update ExtensionManageModel API so that "list" can be processed '''ToBeDone'''
** Update entry "Install Extension from file" to "Install Extensions from file" and support "tar.gz", ".json" '''ToBeDone'''

Meta issue:
* [http://www.na-mic.org/Bug/view.php?id=2779 2779]: Mechanism to keep track of the installed extensions across version '''ToBeDone'''
