* Improve coding style
* Remove useless code comments
* Hide legacy providers by default
* Add Tekstowo to have at least one functioning provider for lyrics again
* Enable query logging only if an environment variable is set
* Use Tekstowo in example JavaScript
* Trigger auto-insert also when query results are available
* Allow to refresh when new search criteria has been (automatically)
inserted
So it is at least a little bit more convenient to use.
* Move query options into menu so it is possible to add more
without being limited by available space
* Trigger the last query action when hitting the enter key
* Change order of elements; I guess it looks better with buttons
and fields to be used at the top
