FileZilla: cloud ftp

I keep looking for a good cloud solution for ftp. FileZilla Portable is ALMOST ideal. You can simply copy it to your Google Drive or Dropbox, etc. and run it from any computer that you have that same cloud app installed. The only problem is that these settings appear to be loaded only once when the program is first loaded and then saved when the program is closed. If you leave the program open on one computer and then try to use it on another computer it gives an error saying that the program was not closed correctly last time it was used. This is also an issue where multiple coworkers are sharing the same filezilla on a shared google drive. It would be idea if the new sites were added "on the fly" opening and closing the settings file as needed. This way multiple users could easily share access to a number of sites without each person having to enter FTP details on their own machine...
