I'm one of those crazy, happy idiots who simply won't stop trying to do something until I've exhausted every possibility and worn myself out in the process. Sometimes it takes a very long time for me to figure out how, kind of like working a differential equation in days of old.
Take for instance, selecting a favorite YouTube video and putting it on my sidebar. Nothing in the gadgets department suited or allowed me to do it the way I wanted to do it. So I gave up for a while and then came back several more times to try something else. And failed again. Well tonight, I hit pay dirt! I got a video of my choice on my sidebar by going through the text gadget and found it works in HTML----sort of. I'm beside myself. Sure you can only see half the screen. But what does that matter if there's great music and you can see all you need to see on the left half!?
I'm going to have some fun with this during Christmas. Anyway if you'll scroll down on my sidebar on the right, you'll see a half YouTube screen. You can click on the little arrow and the video will start up the same as usual. Oh, joy! I have a new toy! A one-armed video.
