In case anyone is interested, I have developed a web app to create .edl files and modified / filtered (family friendly) subtitle files.

https://www.filterflix.com

Regarding the creation of .edl files:

2 .edl files are created.

• One is the regular "ready to use" .edl file.  This is a bit different from the ones we may be used to seeing from the "Open Beta - Mute Profanity" Kodi plugin.  
• There is no preamble of **** which was causing certain versions of kodi to skip the .edl file. (and thus not work)
  The "Open Beta - Mute Profanity" .edl file only listed the word that was skipped which sometimes made it hard to determine if it was an "appropriate" skip or not.  This one will list the phrase so that the word can be seen in context and thus the decision of whether to include the skip or not is easier to make
• The other edl file created here is a "testing" edl.  BIG THANKS to @MovieCleanup for this idea!!!   (See his post here).  He brilliantly created a windows script that would create a testing edl from the regular edl file on your computer. I decided to include the creation of a similar testing edl file (through a different process) automatically at the same time as the regular .edl file creation.
• When you want to use the "Testing" .edl file, the file name needs to be renamed by removing the "TESTING" text and thus match the movie file (and thus the regular .edl will need to be temporarily renamed or moved out of the folder)
• When watching the movie in kodi, The Testing .edl file will have kodi skip the movie to 5 seconds before and a few seconds after every "mute" / filtered word.  This way, you can "test" the timing of the filters as sometimes the subtitles don't exactly match up with the dialogue.  Adjustments can thus be made to the timing of the filter. (Obviously the timing adjustments will need to be made in the regular .EDL file as well!!)
• There is an option to filter ALL profanities (STRICT) or to not filter a list of a few words.  (I could build this out further, not sure yet.)
