Photologo does a nice job and you can size the watermark so that it's unobtrusive. If you use software that can work with layers you can also vary the transparency of the watermark.
Seems like a great purchase that should give you more opportunity to get out and about with camera in hand. I hope it brings you much joy and I'm looking forward to seeing your posts.
I use PT photo edit Two samples one with water marking and other things to it. Here is the website for it...best to buy it if you like it...worth it. www.photo-toolbox.com/free/pt-photo-editor.html
