Would be nice to have a tool window that allows one to graphically edit the app.config, web.config etc files in a user-friendly manner

This is just a "nice-to-have." More of a feature suggestion really.

However, instead of having to remember cryptic .config file commands and to reduce the chance for errors (I just hate it, personally, when software does not work as I expect simply because I typed one character wrong in some config file).

The suggestion is to make the extension add some sort of graphical tool window, or maybe an extra tab onto Project -> Properties in order to alter the config in a user-friendly manner.
