Feature Request: Add a lip to the bin label shelf

[JDMils]

Firstly, fantastic idea, thank you for the addon!
I am struggling to use the label shelves- how do people use them? Do you write the content details directly to the shelf or do you paste a cutout of the packaging onto the shelves?
I'd like to be able to keep the bins in a re-usable format so that I can move the contents of the bin, say it was a 2x2 bin, to say a 3x3 bin as I aquire more parts in different sizes, so what do I do with the descriptions on the bin shelves?
I'd thus like to ask if you can add an option where a tiny, say, 0.4mm edge is added so the bin shelf so that we can place cutout labels onto the shelf without fearing the label will slide off into the bin contents as we open & close our cabinet bin drawers?

And possibly a divider BETWEEN bin labels so the labels don't slide horizontally?

Note: I manually created the 0.5mm lip and found that it interferes with the stackability of the parts bins so it would be prudent to lower the tab heights by the same amount to keep the distance between the bins correct or keep the tab heights and pocket out 0.5mm for the labels to fit in?
