[EKB] This is a simple sliding panel widget (implemented as a [snit] widget).

Here's what the output looks like with three stacked sliding panel widgets. First, with all panes closed:

Then with one of them open:

Here's the code, with the three-panel sample at the end. This is [NOL] - the "no obligation license".
