A while ago I wrote a post about link resolving with DD4T, introducing a GUI extension which allows you to determine which links are followed when a page or component presentation is rendered, and which links aren’t. Unfortunately, the first release of this GUI extension didn’t work with SDL Tridion 2013.
I finally found some time to fix this. To try it out yourself, download trivident.dd4t.editor 1.0.1 and follow the instructions in the README.txt. To view the source code, see https://github.com/trivident/dd4t-editor.
