Based on the original Workflow User Entry Page Finder recipe by David Benson.

On the Workflow Type Configuration page, easily see where a particular Workflow is used.

Lists if a Workflow Type is used in the following:

• Page Blocks with a User Entry form statically configured for the Workflow Type
• workflowactivate Lava in HTML Content Blocks and Block Pre/Post (static/fixed workflowtypeid parameter only)
• General Workflow Triggers
• Connection Type/Opportunity Triggers
• Step Type/Program Triggers
• (more - to be added...)

Steps:

1. Go to the General Settings > Workflow Configuration (/admin/general/workflows)
2. Hover and click on Page Zones (or Alt+Z).  Click the Main Zone, add a new HTML Content block. (name = Where Used)
3. Hover and click on Block Configuration (or Alt+B). Click on Block Properties for the new Where Used Block.  Enable Rock Entity and SQL Lava Commands.
4. Click on Edit HTML for the new Where Used Block.  Copy paste the Lava from below.

<!-- Workflow Type - Where Used block -->
{% assign workflowTypeId = 'Global' | PageParameter:'workflowTypeId' | Default:null %}
{% assign thisPageId = 'Global' | Page:'Id' %}
{% assign hrefRoot = 'Global' | Attribute:'InternalApplicationRoot' %}

Above Lava can be used in Lava Tester - just change the null to a WorkflowType Id

See anything you'd like added? - comment, and I'll try to implement it.
