I’d like to see the ability to use something like CTRL-click on a custom tag (be it struts, JSTL, or a custom tag) and have it open to the entry in the TLD file. Also, when in the editor for TLDs, it would be nice to be able to CTRL-click on the class name and have it open the source code (like the jsp and java editors would do).
[edit]
Also would be nice to have links to the files referenced in the struts-config.xml file.
