Request: checked row highlight style for Listview controls

[v3rt1g0]

I'd love to see the code below included as an easily usable extended style for listview controls.
In a listview with several subitems, keeping the entire row highlighted if the item is checked ($EX_LVS_CHECKBOXES) makes it very easy to quickly scan values in subitem columns.

The example below from user 'rasim' does not use the built-in listview extended style checkboxes, but I would prefer that it did.

Being able to add this functionality as an extended style, without having to delve into WinAPI/GDIPlus would be a huge time saver.
Also having the style work with WM_NOTIFY '$NM_CLICK' anywhere on the row (vs just the checkbox itself) would be perfect.

There's already too much custom behavior as is. If we added all the useful custom behaviors we'd have everything bloated so big it'd be ridiculous.
