Visual tell by tag with filtering

### Problem Statement

I would like to visually distinguish between issues originating from PHP and JS/browser directly in the issues list, but Sentry doesn't blend.

I can clearly see the `logger` tag in the list, but only for PHP. Why? I'm setting the same tag via browser JS with a different value and it appears in the issue detail, but not in the list:

I'm assuming it's the `logger` tag, because it is clickable and activates the filter `logger:php`.

### Solution Brainstorm

I would like to have this option per organisation and per project (ideally), to be able to select one or more "highlighted" tags that appear in the issues list and also provide a quick way to filter by them (by clicking). Then, add the blender.
