What I want seems simple to me.
I want an album art viewer that can be clicked on to play/pause current playback. Something someone has probably written, but I cannot find.
Any help appreciated.
Spider Monkey Panel (foo_spider_monkey_panel) and JScript Panel (similar components) have clickable script that displays album art. I didn't try it but I'm guessing it should be possible to modify the default command to play/pause.
If you install the spider monkey component go to the following folder path under Foobar's profile folder: user-components\foo_spider_monkey_panel\samples\complete. There is a script named album art.js. Load spider monkey into a panel and import this script. Edit the script and add the following statement. I used the middle mouse button because the left and right buttons are being used. If you need more details, let me know.
function on_mouse_mbtn_up(x, y) {
fb.PlayOrPause();
}
