Icon should be inline with panel

The icon – if you draw it dynamically – might have size option where minimum stands for the hardcoded meaningful minimum size and maximum – that of panel's current vertical size minus some pixels; when nothing is set – default to max... I'm not familiar with neither restrictions behind the code, nor applet input elements and how you can control user input, set default values, etc, so please excuse me if that sounds way off topic.

So, overall here's mockup with icons: left being shopped icon, right – current implementation (v2.2beta1):
