It often happens that the developer has a lot of changed sources checked-out from the VCS.
Quite often it has a lot of changed sources which cannot be commited back to the VCS repo.
The developer would like to organize the sources into changelists and give a comment for each changelist (possibly an Issue ID as well for the issue it corrects) before it commits the sources belonging to the changelist.
There may be a special changelist for the sources marked with the "Exclude From Commit" tool of Netbeans.
The sources displayed in the versioning view (e.g.: Subversion\Show changes) should be organized into changelists for easy review.
The sources which are Excluded From Commit, should go to the end of the list into the changelist named "Excluded From Commit".
TortoisSVN 1.6.15 and Eclipse implement this nicely and I strongly believe that Netbeans should do this as well because this is a serious productivity feature.
A complete description on what the changelist feature may look like is available at IntelliJ website: http://www.jetbrains.com/idea/webhelp/changelist.html and the spec thing from subversion is available at http://www.subversion.org.cn/svnbook/nightly/svn.advanced.changelists.html
