Disable/group new file annotations

[arturbosch]

Is there a way to disable this new behaviour?
Or at least group them into one such (expandable) line?

Some older files with multiple formatting issues, stack a multitude of those yellow lines.
This doesn't leave much room to actually read code, so it's quite intrusive.

Aside from that, that settings wheel just shows an empty window.
Not sure if this is as expected?

an example:

We could introduce an configuration option to:

1. Show the old behavior
2. Show the new behavior
3. Just mark the first line / character of the file for such issues
4. New behavior with grouping if possible
