This is a great enhancement. You can now also transfer non fmp12 files from Dropbox to the FMGO directory.
Sky, I have a workaround to import a csv using a webviewer. It takes a little work to set up but it works. A webviewer will not display a .csv file but it will view a .txt file. If you change the .csv extension to txt you can then view the data in a webviewer. Then scrap the contents of the webviewer. I then use a script to parse the comma separated data and create records into a temporary import table. After that you can import from the temporary table.
