First of all, a number of plugins need to be updated for the new icon set; right now they either look out-of-place or icons don't show up at all. This includes AntFarm, Sessions, JBrowse, AntViz, and maybe others.

Also, I would really, really, like to see someone step up to either take over CodeAid and Jane, or start from scratch to write a code completion plugin that actually works.

I would also like to see ProjectViewer and Gruntspud improve to the point where they are usable for day-to-day work.

I am new member of JEdit commuity and using JBuilder I noticed that with JEdit it is not possible to create GUI like JBuilder does.
Would that not be a good idea ?

There is a new release of Gruntspud, a graphical CVS client that may be used as a plugin to jEdit or as a standalone. This release sees loads of new features, commands and bug fixes as well as a Java Web Start installer for the standalone version. Note: Gruntspud now uses the 4.0 plugin API..

This release containes fixes for the :pserver problems, new actions such as Log (with a useful report dialog), Import, History, Erase. There are some extras such as a 'New Folder' action that creates a folder then adds it to CVS and a simple .cvsignore front end (although the filter is still rubbish). There is a 'Explorer' style view that can be used instead of the Files / Folders tab when there is more space available.

The toolbar is getting quite large now, so an 'All tools' button hasbeen added to help when docked in jEdit, but I'm not 100% happy with. Suggestions are welco

If you have this error try to rename XML.jar to aXML.jar. It solve it on my machine.

Slava says: indeed. The reason is that XML sets a couple of system properties in its plugin start() method, and if it happends to be loaded after SQL, then the SQL startup might fail. The author of this story says he is working on a patch and will send it to the SQL plugin maintainer over the weekend; so this is just a fix you can use in the meantime.

If you want to stay on the bleeding edge, check out some of the plugins that have been recently added to the 'Beta Plugins' section: namely, Velocity Plugin, IRC 1.8, and LaTeX Outline Plugin.
