ListView static headers & footers, grouping and unbound mode support

I think this is a good use-case, for the following features:

• Support unbound mode in ListView #262
• Enable grouping on ListView #259
• Allow ListView init by directly specifying its items without template and collection #104

Our “Expensity” application has the following design for iOS:

Which in iOS can easily be created using Xcode’s IB with UITableView that has Content of Static Cells. The following is a screenshot of an attempt to recreate the above design in Xcode with static cells:

I would expect something like the following code, to be able to recreate what is possible with Xcode’s storyboards:

<Page xmlns="http://www.nativescript.org/tns.xsd" 
      loaded="pageLoaded"
      navigatedTo="navigatedTo">
  <Page.actionBar>
    <ActionBar title="Xpensity">
      <ActionBar.actionItems>
        <ActionItem text="Sign up" tap="signup" ios.position="right" android.position="actionBar" />
      </ActionBar.actionItems>
    </ActionBar>
  </Page.actionBar>

  <ListView>
    <ListViewSection>
      <ListViewCell>
        <TextField hint="username" text="{{ username }}" />
      </ListViewCell>
      <ListViewCell>
        <TextField hint="password" text="{{ password }}" secure="true" />
      </ListViewCell>
    </ListViewSection>
    <ListViewSection>
      <ListViewCell>
        <Button text="Login" tap="login" />
      </ListViewCell>
    </ListViewSection>
    <!-- list-view footer -->
    <Button text="Forgotten password?" tap="resetpass" />
  </ListView>
</Page>

Currently the effect is achieved with a bunch of Border-s and CSS.

I would be very interested in this feature as well.

Can we get the floating headers?:
