   * **Interface Customization** ​ Greenstone3 replaces macros with XML and XSLT for customising the visual appearance of your collections. This affords users more power over the look-and-feel of collections. The library program generates page data in XML, which is converted to HTML using XSLT. All formatting is done using XSLT, so it makes it easier to customize than Greenstone2 in which some of the HTML is output by the library, and some by the macro files. It is very easy to get back the data in XML, if you want to use it for other purposes. ​   * **Interface Customization** ​ Greenstone3 replaces macros with XML and XSLT for customising the visual appearance of your collections.

-  * **Berry Baskets** ​ Berry Baskets offer a way to gather documents of interest while browsing Greenstone collections. When you turn the facility on from the Preferences page, a basket appears in your browser window. Now, whenever you see a document that interests you, you can drag-and-drop it into the basket. Later, you can review the basket'​s contents, and cut-and-paste ​them into an email. (Note, the "Send email to a friend"​ button does not work yet. Also, it works best under Firefox, rather than Internet Explorer.) ​+  * **Berry Baskets** ​ Berry Baskets offer a way to gather documents of interest while browsing Greenstone collections.

   * **Cross-Collection Search** ​ Cross-collection searching in Greenstone3 is provided across all collections by default. Collections are no longer required to have the same indexes, as the default index is used for each one. However, this means that you can't select which indexes to search, and search result ranking may not be valid as different indexers rank results differently. ​   * **Cross-Collection Search** ​ Cross-collection searching in Greenstone3 is provided across all collections by default.

   * **Multiple sets of collections and multiple interfaces** ​ A single Greenstone3 installation can have multiple sets of collections and multiple interface definitions. Greenstone2,​ on the other hand, has a single collect directory, and a single set of macros. Greenstone3 has multiple "​sites"​ each of which has its own collect directory, and multiple "​interfaces"​ each of which has its own set of XSLT files. Any site can be served using any interface. ​   * **Multiple sets of collections and multiple interfaces** ​ A single Greenstone3 installation can have multiple sets of collections and multiple interface definitions.

-As Greenstone3 is still in its early stages of development,​ a number of problems and bugs remain. If your Greenstone2 collections do not work under Greenstone3,​ or if you are experiencing some unexpected behavior from Greenstone3,​ please read this list before contacting us. + 
-  *   **Conversion of ''​collect.cfg''​ **  Greenstone3 still uses Greenstone2-style ''​collect.cfg''​ files internally, and converts these to Greenstone3-style [[http://​en.wikipedia.org/​wiki/​XML XML]] files called ''​colletionConfig.xml''​. Unfortunately,​ the conversion is not always perfect, and may cause some unexpected errors with your collection. As development continues, the conversions will get better. Eventually, Greenstone3 will work solely with ''​collectionConfig.xml''​ files, eliminating the need for this problematic conversion process.  +  * If you have heavily modified macros/format statements ​using greenstone 2 then it can be tricky to achieve ​the same thing in Greenstone3. ​HoweverGreenstone 3 is much more customizable once you do know how
-  *   ​**Collections sometimes disappear after changes to format statements**  After changing a format statement in a collection, ​the collection may become unavailable. ​ This is because the conversion of the ''​collect.cfg''​ file after the new format statement is introduced produces a ''​collectionConfig.xml''​ file containing malformed XML. A collection cannot be hosted ​in Greenstone3 ​without a valid ''​collectionConfig.xml''​ fileso the collection disappears from the library. The solution ​is to undo the edits which caused the problem.  +  *   ​**Need to click preview after changes to format statements** ​ Unlike in Greenstone2, ​the collectionConfiguration file is loaded into memory when the library server starts upChanges ​to the file require ​the collection ​to be reloaded in Greenstone, or the server restartedClicking ​the "​preview ​collection" ​in GLI will do this for you  
-  *   ​**Need to click preview after changes to format statements** ​ Unlike in Greenstone2, ​format statements are not applied automatically to their collectionsTo apply changes ​to format statements, you must click the '​Preview'​ button in the GLI to invoke an internal conversion script which applies the changes.  +  *   ​**Export to CD/​DVD-ROM** ​ Exporting collections to CD-ROM and DVD-ROM is not supported in Greenstone3's GLI. However you can make a DVD yourself, see [[ http://​wiki.greenstone.org/​doku.php?​id=en:​user:​exporting_collections#​can_greenstone3_export_to_cd_dvd-rom_collections|this page]].
-  *   ​**Nested ''​if''​s and ''​or''​s** ​ At this stageGreenstone3 can only handle ''​if''​ and ''​or''​ statements in its format strings which don't contain other ''​if''​ and ''​or''​ statements. If you try to nest ''​if''​ or ''​or''​ statements, some of the control characters (like the curly brace '​{'​) will be interpreted as literal characters and will appear on the pages of your collection +
-  *   ​**Refresh Error in the GLI**  After building a new collection in GLI, it may not appear in your Greenstone library. If this happens, check that your **Greenstone Web Path** is set correctly (File -> Preferences... -> Greenstone Web Path). For the default installation,​ this should be set to ''<​nowiki>​http://​localhost:​8080/​greenstone3</​nowiki>'' ​ +
-  *   ​**Export to CD/​DVD-ROM** ​ Exporting collections to CD-ROM and DVD-ROM is not supported in Greenstone3. ​+
