Popup comments

The ability to mark a section of text to have a popup comment associated with it.
The user would hold a key while mousing over the section to reveal the comment.
Markings on the left margin could be added to denote areas of comments, each with their own color

This can help prevent things from being cluttered while still keeping the ability to have code annotated in some form

Yes, would be nice.

I would especially like to comment a specific part of a line without needing to break up the line with comments or attempt to align the columns of a text comment above some code that you are trying to highlight.

It might be best to store such info in markup in normal text comments and just have the IDE display appropriately.
