Enrich user profiles via plugins

[macobo]

Is your feature request related to a problem?

There are a lot of features which are useful from a "build a successful company" or product analytics standpoint, but which are niche enough to become hard to build into core posthog.

Some example features are:

• User interviews product User interviews product #2880
• Including information from other tools in posthog (e.g. hubspot links, notes, stripe profile link, etc).
• Show survey results from Allow extending posthog.js via plugins #3504

It would be great to build these out as plugins.

Describe the solution you'd like

Allow to define "user profile" plugins which:

• Can inject custom HTML/JSX into the profile page.
• Optionally define some user properties which are not displayed the normal way.

For example, a user interviews plugin could:

1. Store notes in either custom events or user properties
2. After user page is rendered, plugins renderUser() method gets put onto the page - containing things like interview note editor which pulls data from our API and captures an event when editing is done.

Describe alternatives you've considered

Building this into core posthog.

Idea from call with customer today. Curious on your thoughts @mariusandra @jamesefhawkins @Twixes @yakkomajuri

Thank you for your feature request – we love each and every one!

Indeed I believe @mariusandra has mentioned wanting to have UI plugins before, and it's something I myself was thinking of very recently too.

Would be super cool but realistically I think there's at least a few release cycles of plugins work left before we think of building this.

No rush. :) Just documenting ideas.

I understand!
