add footer

[z-vr]

This PR adds a footer. Could be useful to put something like loading indicator.

I'm sorry, I've totally missed this one. I like it, good feature, can be really useful. Is it possible for me to contribute to your PR (have never done it before)? Or do you have time to make it compatible with the latest updates/code changes?

Either way, thanks!

[z-vr]

@tbleckert hey I've updated the PR -- you'll have to rebuild the dist though!

[tbleckert]

Awesome, thanks!

What do you think about making the footer a separate layer below the buttons? Something like this

Title
Body
Buttons
Footer

Just an idea I got and wanted to hear your opinion about it.

[z-vr]

@tbleckert hey, the way we use it is to place a loading indicator in there, e.g.,

I feel like if there appears an extra area below the button, it would make the form jump if you get what i mean? It's probably possible to configure this kind of footer as you mentioned because it does look cool on the image above.

[tbleckert]

Ah ok I see. What do you think about having the buttons arrays accepting components as well (not only button objects)?

{
    left: [<LoadingIndicator />],
    right: [{
        text: 'Add',
    }]
}

That way you also get more freedom when it comes to adding buttons.

And then skip the footer idea I had or have it as a second new feature.
