Feedback Request: Custom Visuals V1 APIs Suggestions

I'm not really following what you mean by a "Custom Visuals API" - can you elaborate? Custom Visuals as I currently understand them dont have anything I would term an "API" - its just some source code and some brief guidance on how to use it. 

Anyway IMO most of the current issues/challenges are not to do with the technical implementation but rather the documentation content around that - we need detailed documentation on the objects/properties we can use, how-to, walkthroughs etc.  It is too hard to get started and too obscure once you do get in.

Also I think the publishing process needs a lot of work.  The code of Custom Visuals should be vetted by Microsoft and then published e.g. to Github before being listed in the gallery. This would include clear licensing. You should then remove the current absurd "security theatre" of asking the end user to certify the security of code they have no access to (even if they did have the skills to judge it).

Also the Custom Visuals gallery itself is almost impossible to find, even if you know it exists.  It doesnt seem to be listed in the powerbi.com site navigation anywhere or even on sub-sites/pages where you might expect to see it linked e.g. https://powerbi.microsoft.com/en-us/custom-visuals/ .  It is not included in the Community search results. I always have to use Google to find it ...
