I have stumbled upon a minor difference in behaviour between PM V6 build 5029 and PM+ V6 build 5376 on Windows 10 which is tripping me up (that is, breaking my normal workflow).
I use Text Exporter to transfer selected metadata for external use. I format the output as xml and name the resultant file something like 'data.xml'. PM lets me do this but PM+ insists on naming the output file 'data.xml.txt'. That is, it adds a 'txt' extension whether I want it or not.
I expect that you would want the behaviour of PM and PM+ to match. I very much hope that you choose the PM behaviour.
I realize that when I set this up, I could have chosen to use the xml exporter but the text exporter is a much simpler solution for me.
