Basically as I saw the issue, DrByte, was that it is desired to offer a link in the Developer's ToolKit when the results are provided. The link would locally open software "known" to be on the computer. The link would direct opening the destination file(s) preferably to the point at which the result was found. At a minimum to open just the file that has/had the result in it.
Seemed to me possible to program into the Developer's ToolKit as an additional link containing the application "call-out" as part of the displayed results. As eluded by swguy, perhaps this application can manipulate remote side software; however, there is always the issue/concern of directly modifying a live site instead of a development site. Successful changes made to the development site to then be merged into the live site. The live site therefore would have little to no need to incorporate this functionality. Additionally, such feature may not work from another computer if the software (Notepad ++ or whatever tool is to be used) does not exist on the computer accessing the admin's Developer ToolKit.
