About the log doc
The log document is a simple text file. It provides the list of all the stored tags and the list of all the videos that have been edited using the add-on. It is formated to be pasted into a spreadsheet.
It's a working document meant to be shared and annotated by co-workers.
Too many references!
If you don't want to mix several projects references, you may need to 'create a new log file' (from the menu) before working on a new project. It will save your metadata into a folder called 'Easy logging files' in your Home directory. Then a fresh new metadata file will be created for you.
