Is your project explorer stuffed with too many projects? Are you looking for a way to get more structure into this? I was suffering from this problem for a long time now, having workspaces with 50+ projects in it. I am using Working Sets and Mylyn, still I sometimes get lost within all my resources.
Resource Decorator Plugin
So I came up with a nice little plugin that allows to add custom decorations to your resources. Eg you could set a dedicated background color for all your projects that fit to a dedicated name pattern. You could also set the foreground color for all your src folders or highlight plugin.xml files.
The Resource Decoration is accessible through the Navigator context menu, which contains some quick decorations and a generic wizard that allows to fine tune your settings. There you can build generic filters by creating a tree structure. The Resource filter will match a resource path within your workspace. This will always be an exact match. The RegExp filter takes a regular expression to match it against the resource name. You have to use drag and drop to build your filters, DEL will remove a selected filter along with its children.
To alter decorations you can go to Preferences / General / Appearance / Resource Decorator. Take care that the Resource Decorator is enabled in Preferences / General / Appearance / Label Decorations (which should be the default setting).
The tool is at a very early stage as the interface is a little rough and filtering is a bit limited so far. Yet it is working, save and quite useful to me.
