Thanks Caleb, I'll take a look at this next week.

@johnbillion Could it be that week spans 3 years :)

Coincidentally I was looking at this ticket last night, after working on improvements to the Scripts and Styles panels in thedevelop branch recently, and closing some old issues.

I'll leave this open for now but it will need refactoring. I do want to add a way of exposing the extra data associated with scripts and styles.

@johnbillion btw I've been working on a "asset whitelist" plugin, and it would be really nice if I could easily highlight (red - blocked, or green - whitelisted) specific blocked asset identifier slugs somehow.

@lkraav QM does this for assets blocked by the Airplane Mode plugin, which works by converting the source URL into an Airplane_Mode_WP_Error object which is just a WP_Error object with a __tostring() method on it. You could do something similar. Does that help?

[crstauf]

@johnbillion @szepeviktor Updated the branch with develop, and added the column back.

@johnbillion Maybe we are 1 click away from merge.

I'll make the necessary adjustments to pass the tests this weekend.

Fixes made.
