Starting with the 12/9/2022 Nightly build, there will be a way to display the volume of the Cylindrical Tank as a pure volume, as opposed to a percentage of the capacity. The driving properties for this new display option are within the `valueDisplay` object:

```auto
{
  "enabled": true,
  "format": "0%",
  "unit": {
    "enabled": false,
    "value": "",
    "fix": "post"
  },
  "style": {
    "classes": ""
  }
}

```

Note the addition of a `format` property and a `unit` object, which contains several additional properties. These settings default to these values to assure that existing Cylindrical Tanks display as they always have, where the displayed value has always been a percentage of the `value` against the `capacity` props.

The `format` property provides helpful enumerations of probable formats (percent, none, integer, currency), but accepts any string format you'd like to provide. If the `format` property is unable to meet your use-case, the `unit` object provides for more fine-tuning of the displayed value, including the ability to prefix or postfix units onto the `value` property when displayed. The `value` property of `unit` will be attached as either a prefix or postfix to the displayed value _even if a formatting option is applied_ as long as `unit` is enabled. This allows for displaying values however you like, including "H20 50%"

The following screenshot provides some examples of different settings and how they are applied to a Cylindrical Tank:

Instance 1:

- Default display properties.

Instance 2:

- No formatting applied ("none"), so the `value` property is displayed as a pure value, regardless of the `capacity` value. Note that the liquid continues to display as a percentage of the available space, so you should still manage your `capacity` value to reflect the available space of the tank.

Instance 3:

- Default settings, but it's worth noting that the `value` here is greater than the `warningThreshold`. The `warningThreshold` has always been and will continue to be the _percentage_ of fill at which the Cylindrical Tank should display a warning. Again, this is unchanged, but some users might have assumed the `warningThreshold` was intended to be the limit of the `value` which would trigger the warning appearance.

Instance 4:

- Here, we see the same values as Instance 3 but with a lower `warningThreshold` which has been exceeded by the percentage as a calculation of `value` over `capacity`, and so the warning appearance has been applied.

Instance 5:

- Here, we are applying the "integer" formatting, but we have also elected to provide our own units ("L") as a _postfix_ to the displayed value.

Instance 6:

- This example shows how to use a unit value ("$" in this instance) as a _prefix_ to the displayed value.
- This example is similar to use of the "currency" formatting option, but note the lack of displayed trailing decimal places.
