I'm using phpStorm and have a perl script as part of my codebase. When I open the perl script in phpStorm, I notice two things I can't figure out. (see screen shot be;low)
1. What's the little arrow in the left column by the line number?
2. Why does it default to comments collapsed under "comments..." ??! So weird.
Note that in PHP code, none of these things show up.
