I’m planning on writing some blog posts wich will show how to add custom sections and custom trees to the umbraco v4 backend. I was looking for a simple example and thought about adding a custom tree wich allows to edit the umbraco config files. So that post will folow but in the meanwhile I made a package of that example (only took 2 minutes to package it up, umbraco v4 package creator and package actions rule!).
The package will add a new tree to the developer section. Wich lists all *.config files. The config files can be edited. That’s pretty much it.
