Good tip on adding groups to Coverage report. Also, I didn't know about to filter not used files, as channels stuff.
But I wanted to remove Channels, Jobs and Libraries tabs from report.
I found this way looking at [Coverage source](https://github.com/colszowka/simplecov/blob/master/lib/simplecov.rb)
```
SimpleCov.start 'rails' do
# add filter removes files from coverage, but not tabs in report
add_filter 'app/channels/'
add_filter 'vendor/'
add_filter 'app/jobs/'
# remove tabs in report
groups.each do |group|
groups.delete(group.first) if %w(Channels Jobs Libraries).include? group.first
end
# add my onw tabs in report
add_group 'Datatables', 'app/datatables'
add_group 'Policies', 'app/policies'
add_group 'Presenters', 'app/presenters'
end
```
