Thanks to Husse, FedoraRefuge and Melwiz79 for your responses. I am aware that you gentlemen and a, hopefully "vast" number of others are all working hard on the many facets of Linux Mint, including XFCE, and doing a great job. As it appears that there will be a "RC2" in the very near future, I shall wait for it. When it's available, download and install. The final version, as stated, should then come with only some minor changes/updates which, hopefully, are easy to download and install in the RC.
I can hardly wait.
