I’ve lately worked a lot with property files and what always bothered me was that there was no Outline-View shown for it like it is e.g. for the Java-Files.
Typically properties-File e.g. for translations are structured in a hierarchical way e.g. my files look like this:
ListView_FirstName=First Name ListView_LastName=Last Name DetailComposite_Title=Title DetailComposite_Name=Name
I’ve uploaded the Eclipse Plugin to EclipseLabs and you can install it by pointing your Eclipse Plug-in Installer to http://outlined-property-editor.googlecode.com/svn/trunk/updatesite/.
