Excellent. Took me a while (total newbie) to stop hunting for a file called "Commands.sublime-commands" on my hard disk and look at the source for your package. Now all good!
I wonder if a mechanism to automatically split text into multiple files based on a regex pattern might be beneficial to anyone else... ie...
1. user builds a regex pattern
2. user tests the selection a few times
3. user invokes the "split to files" command
4. 1+ files are produced from search results in a designated directory
course, I have no idea how to do that... hint, hint
