[Feature Request]: Multi Column Combo Boxes

[MattH-Work]

Simple request, multi column combo box

Tried various 3rd party options (both open & closed source), but none look right
I would like a Krypton multi column combobox as it would have the same look and feel of the standard Krypton combox (and be consistent with other Krypton controls) and also enjoy the same additional functionality (ButtonSpecs & the new rounded corners being a particular favourite)

[MattH-Work]

current Krypton combox with rounded corners and an additional 'embedded' button (via ButtonSpec)

standard combobox customised to have multiple columns (note the seperate button, used to 'fake' the buttonspec from the above image and the lack of rounded corners)

Also related to #123
And #135
And #102 102

Bumping to try to get this back on the radar

Rolled my own, but would still prefer a Krypton 'first class citizen'

Is this a v100 thing?

At least but rather 110...
