just started, https://github.com/SublimeText/FindResultsApplyChanges
Basically, you have a "tab" named "Find Results"(standard 'file results' from ST), and any change made to the content of that tab, can be applied back to the files, by going to "Main menubar" -> "Find" -> "Find Results Commit Any Change Made".
Today, is a quick and dirty hack. Is just a start, pull requests welcome....!
Just in case, will only apply changes to these lines starting with numbers. ;-P
