Implement configuration UI

This module seems very promising, but not very usable without a UI I'm afraid. Any idea on when it will be finished. Anything we can do to help? I kind of want to use this to use a view with exposed filters as an entity reference widget, but currently have no clue how to set this up.

If there's anything I can do to help, let me know and I'll see what I can do.

One thing I would mention even if the UI isn't in place documentation of the configuration to use to run in the config sync would be useful.

A simple yml file describing what belongs where aka:

```
name: test
label: 'Test browser'
display: standalone
display_configuration:
.......
```

If that could be added to this thread with multiple examples it'll make testing this module a lot simpler for people just getting up to speed with it :)

Super useful. Thanks.

Ok i do not hesitate :) and i start working on this.

I make new commit on latest pull request for config ui. There is some changes for fixing ajax callback and widget weight.
https://github.com/drupal-media/entity_browser/pull/137

I make another commit and i think saving widgets configuration now is ok.

This looks like the sort of thing that would benefit from configuration defaults. Take a look at implementing ConfigurablePluginInterface. You're most of the way there already just from what I see in the patch.

Otherwise the patch looks pretty good. I'll apply it and give more feedback shortly.

I was able to get a config for a entity browser working using this patch. But the process seemed quite bulky. I had a lot of empty steps in the wizard and especially the step for selecting the widgets was quite confusing. Should I provide more feedback about this or is this currently not needed?

Makes sense. The patch doesn't apply anymore. Here is a re-roll.

After install the latest dev version I'm getting this error. I ran updb and clear cache. What else could be?

The website encountered an unexpected error. Please try again later.

The list handler may need overriding for creating the proper edit button.

Sorry for the delay.

This was the old entity.browser yml files.

I had those two already installed. What I'm missing on those two?
