## Settings
Settings are the different options a user may set or experience in the application. These are pre-defined in
`src/settings/Settings.js` under the `SETTINGS` constant and have the following minimum requirements:
```
// The ID is used to reference the setting throughout the application. This must be unique.
"theSettingId": {
// The levels this setting supports is required. In `src/settings/Settings.js` there are various pre-set arrays
// for this option - they should be used where possible to avoid copy/pasting arrays across settings.
supportedLevels: [...],
`src/settings/Settings.ts` under the `SETTINGS` constant, and match the `ISetting` interface as defined there.
// The default for this setting serves two purposes: It provides a value if the setting is not defined at other
// levels, and it serves to demonstrate the expected type to other developers. The value isn't enforced, but it
// should be respected throughout the code. The default may be any data type.
default: false,
// The display name has two notations: string and object. The object notation allows for different translatable
// strings to be used for different levels, while the string notation represents the string for all levels.
displayName: _td("Change something"), // effectively `displayName: { "default": _td("Change something") }`
displayName: {
"room": _td("Change something for participants of this room"),
// Note: the default will be used if the level requested (such as `device`) does not have a string defined here.

## Features
Occasionally some parts of the application may be undergoing testing and are not quite production ready. These are
commonly known to be behind a "labs flag". Features behind lab flags must go through the granular settings system, and
look and act very much normal settings. The exception is that they must supply `isFeature: true` as part of the setting
definition and should go through the helper functions on `SettingsStore`.
Feature flags are just like regular settings with some underlying semantics for how they are meant to be used. Usually
a feature flag is used when a portion of the application is under development or not ready for full release yet, such
as new functionality or experimental ideas. In these cases, the feature name *should* be named with the `feature_*`
convention and must be tagged with `isFeature: true` in the setting definition. By doing so, the feature will automatically
appear in the "labs" section of the user's settings.
Although features have levels and a default value, the calculation of those options is blocked by the feature's state.
A feature's state is determined from the `SdkConfig` and is a little complex. If `enableLabs` (a legacy flag) is `true`
then the feature's state is `labs`, if it is `false`, the state is `disable`. If `enableLabs` is not set then the state
is determined from the `features` config, such as in the following:
Features can be controlled at the config level using the following structure:
```json
"features": {
"feature_lazyloading": "labs"
"feature_lazyloading": true
}
```
In this example, `feature_lazyloading` is in the `labs` state. It may also be in the `enable` or `disable` state with a
similar approach. If the state is invalid, the feature is in the `disable` state. A feature's levels are only calculated
if it is in the `labs` state, therefore the default only applies in that scenario. If the state is `enable`, the feature
is always-on.
Once a feature flag has served its purpose, it is generally recommended to remove it and the associated feature flag
checks. This would enable the feature implicitly as it is part of the application now.
When `true`, the user will see the feature as enabled. Similarly, when `false` the user will see the feature as disabled.
The user will only be able to change/see these states if `showLabsSettings: true` is in the config.
### Determining if a feature is enabled
A simple call to `SettingsStore.isFeatureEnabled` will tell you if the feature is enabled. This will perform all the
required calculations to determine if the feature is enabled based upon the configuration and user selection.
Call `SettingsStore.getValue()` as you would for any other setting.
### Enabling a feature
Features can only be enabled if the feature is in the `labs` state, otherwise this is a no-op. To find the current set
of features in the `labs` state, call `SettingsStore.getLabsFeatures`. To set the value, call
`SettingsStore.setFeatureEnabled`.
Call `SettingsStore.setValue("feature_name", null, SettingLevel.DEVICE, true)`.

### Features
Features automatically get considered as `disabled` if they are not listed in the `SdkConfig` or `enableLabs` is
false/not set. Features are always checked against the configuration before going through the level order as they have
the option of being forced-on or forced-off for the application. This is done by the `features` section and looks
something like this:
```
"features": {
"feature_groups": "enable",
"feature_pinning": "disable", // the default
"feature_presence": "labs"
}
```
If `enableLabs` is true in the configuration, the default for features becomes `"labs"`.
