I just filed a feature request asking for us to be able to put our own control templates into the library: <https://xojo.com/issue/33409>
There are a handful of controls we create frequently that I’d love to be able to simply drag out and have configured. I think everybody has different requirements, that’s why I’m asking for a flexible option, rather than simple requests for things like “a bold label” or “a 32x32 progresswheel” or whatever.
