A while ago I suggested a similar feature https://forum.sublimetext.com/t/ad-hoc-tool-integration/881/1.
I am using a lot of different command-line tools that output file locations e.i. file name and line no. I added some of these tools to the build menu, but it didn't really work me, because I often tweak these commands with command-line arguments and options. So I abandoned this approach after I've added more than 20 basic command-line combinations to the build menu.
At the moment, I am just using one "build" command (Replay.sublime-build).
build cmd.exe /C type output
I use this command to replay the output from the last shell command I ran outside Sublime. This actually works reasonable well for me, but I still believe that Sublime is missing a tool panel that would allow us to type in ad-hoc commands (see my last post).
