The newly introduced Query Dependency view is phenomenal but what we really need is a Measure Dependency view. Here is what it might look like: http://ppvt.pro/2eXKndh
And a video detailing this idea: https://youtu.be/sYjBB_Ef66M
In one of my production models I have 60 Queries, but I have 200+ measures! I believe that is typical; usually I build Queries and Measures as lego blocks, combining simpler ones into more complex ones needed in the end. In fact I needed it so badle that I attempted to build a Measure Dependency view using NodeXL. While that works, it's a lot of heavy lifting. How cool would it be, to just click a button on Power BI Desktop and see all your measures in a Dependency tree!

Also being able to ctrl-click [Measure name] in the editor to navigate to this measure would be great!

A dependency tree until you reach fields.
And also for calculed columns against other mesures or fields

With XMLA endpoint on Power BI datasets (Premium), you should be able to get the dependencies using a query like this:
SELECT * FROM SYSTEMRESTRICTSCHEMA ($SYSTEM.DISCOVER_CALC_DEPENDENCY, [KIND] = 'NAMED_DEPENDENCY')

RE: Measure Dependency View (similar to the Query Dependency View)
Avi, great idea. I posted the following before I saw that it was a very similar suggestion...
Measures that reference and depend on other measures can be difficult to trace and debug. To make this easier, provide the option in the field list to show the measures that are referenced by other measures. This should be optional and performed individually for each measure to avoid unnecessary performance overhead. Here's a conceptual mockup:measure dependency (on my blog here: sqlserverbi.blog/2019/08/06/power-bi-product-suggestion-show-measure-dependencies/ )

Definitely need this on Measures.

This kind of functionality is crucial for building complex reports!

More than a year later and this is still the best tool out there https://github.com/otykier/TabularEditor

Great idea, where is it?!

Impact Analysis, dependency, data lineage - all about tranparency into the data, understanding and trusting the data used in analytics. Enhances users' ability to create robust, meaningful analytics and drive business conversations and decisions.
RE: Measure Dependency View (similar to the Query Dependency View)
Once we have the dependencies, they should also be used when it comes to updating calculated tables/columns after changing e.g. a measure.
Changing a measure should not trigger a recalc of a calculated table where that measure was not used at all // has no dependency to
