Allow users to enable/disable workflows

Allow users to disable workflows

We currently have the disable trigger feature in the trigger configuration modal but it is not visible enough for users to find. For this project, the behavior of disabled triggers will not change but we will make it more visible and easier for users to locate.

This new feature will be placed in the workflow configuration modal and allow users to toggle a workflow on or off by using a toggle with the icon. (See below)

Creating a new workflow

When a user creates a new workflow, the workflow should be disabled by default and the user should manually enable it when they are satisfied and ready to go live.

Editing a disabled workflow

When editing a disabled workflow, we should show an indicator that tells the user that the workflow is disabled.
