Support for arbitrary values

[alecglen]

Hi Marcin,

Thank you for this great widget design! I started using it in my app recently, but I soon needed to also select a category and wanted to use the same design. I couldn't think of a good way to integrate this functionality within the scope of your widget, and I wanted to keep moving on my app, so I forked your project and made WidgetPicker (currently it only supports strings, but I named it with the intent to add support for things like images in the future).

I wanted to let you know since I see there are a few others asking for this functionality in adjacent issues. If you can think of a way to integrate them, I am open to that. Otherwise, please feel free to recommend WidgetPicker to your users as a resolution to those issues!

Cheers, Alec
