Symphony 2.3 – Select box interfaces

Different browsers and OSes come with different UI components for select boxes, checkboxes and radio buttons. The main idea is to provide a set of standard elements that are rendered in the same way on all browsers and OSes.
In some cases a standard select box can't handle a long list of options (e.g. timezones, countries, and so on). It would be better to have a search interface to quickly get the desired option. See Chosen for an example.
Both Stage and Reference Link Field provide similar features for browsing/searching items. Reference Link Field also provides autocompletion, which is a useful addition.
Better Forms is an attempt to support all the above features. It's uncomplete and still in beta. Shall we improve it or stick to external plugins like Chosen?
