Horizon Dashboard - Configuration/UI

The new Horizon experience is awesome when creating a brand new dashboard, however, when attempting to modify existing dashboards due to process iteration, the experience becomes somewhat frustrating due to the adaptive interface. 

Would any of the following be possible?

• “Freeze” the location of reports as the dashboard is configured
• Return the classic UI ability to switch the location of 2 reports cleanly
• Drop widgets/reports into available space instead of at the bottom of the dashboard
• Toggle the adaptive UI vs freezing

We have several dashboards with 10+ reports, and the adaptive interface shuffling the location of most/all reports when trying to drag & drop adds significant time & effort to replace the layout before saving.  Smaller dashboards are easier to work with - but the UI seems to be designed more for initial build than continuous improvement & iteration.
