Don’t know if this is the best way to add to the panel wishlist, but had a client today ask for a “popup: true” checkbox in the kirbytext link builder button. That way they don’t have to go into the code and remember how to make some pages open in a new tab.
I’m very critical with this feature as a default. target=_blank is something you should use very carefully and rather convince clients not to use it in the first place. I know from my own clients that this wish comes up over and over again.
But if you really need the button, copy the textarea field from the panel source and create your own custom textarea field. You can even keep the textarea name for it. Since 2.2.3 fields now have their own ways of adding modals, so you can modify the buttons as well as the modal and add the additional form field.
I didn’t know about the host attribute for links until now. This is really cool and powerful. I especially love that it’s in the spirit of progressive enhancement. If your clients really WANT it, you can add it, but it won’t modify your code. So it’s super easy to strip out, once your clients start to understand the web better
