Difficult to debug events when there are many of them

[DarkPark]

The request

Having a lot of devices and trying to debug state changes on the page Developer Tools -> Events I see huge amount of events from all devices. It's very difficult to find the device I'm interested in in this pile.

The alternatives

I'd like to suggest to add additional filters - not only by event type but by event content, entity_id, friendly name and so on.
It's also would be nice to be able at any moment to clear all the events dumped (new button Clear).
Even better - table view for events with separate columns for event type, event data, time, origin, context ... With ability to filter each column of course.

We should add a search box and filter
