Hey thanks so much :-)
this is great & does almost exactly what I want. I't took a little playing around to get it to work for me as I'm basic & don't really understand the tech' much at all but with your extensive help files & a bit of time & experimenting it's going good, I nearly had to go looking for a youtube video or email the author for help but with a bit of patience & bumbling around I worked it out. One of my newb mistakes was having it probe a picture element instead of text, although I could see that what the picture was of had changed pageprobe could not as I think it only looks at the size of the picture and where it is hanging which I don't think changes, soon as I changed to monitoring the pictures text description it worked fabulous. I couldn't get the sound notifications to work & the popup notification disappears even tho I have it set to no timeout but I'm pretty sure that's just my old firefox esr version, anyway it's no big deal & probably would just give me a fright like the auto loading tabs did the first few times I got it working :-D

+1 for the root directory request or pinning the general folder open.
