Support for Anchor Comments

Hi,

On VSCode I am using this plugin - https://marketplace.visualstudio.com/items?itemName=ExodiusStudios.comment-anchors

It makes it really simple to have file "sections", really useful for large files to put part of the code into category, and being able to browse it from the side panel, to jump back and forth between parts.

I am looking for something similar on Webstorm, there's the option to overload the TODO option to use that, but it still being categorize under TODO. - https://www.jetbrains.com/help/webstorm/using-todo.html

It would be nice to add another category next to the TODO, or even at the side panel for that type of marked comments.
