GIMP 2.10 - Trouble Painting or Cloning On Top of Alpha

[TMORT]

I did look at the video. Actually, I found the answer in the first minute or so. it may also had a lot to do with I gave up circling around and gave up for the day and posted my post and did other things/slept on it.

I guess I'd managed to lose track of what layer was where and which one is active.

Just wondering now if in the layer dockable panel there is any indication of the order of the layers, which one is currently selected, etc.

Thanks for the reply.
