Difficulty after plugin uninstallation

Hi Jeff,

I’ve uninstalled Prismatic plugin six month ago.

I wish plugin should have reverted my code block to original position otherwise shouldn’t have made fatal changes in first place.

Now, the lefthover is creating difficulty in editing code block.

This is a step #1 of plugin guidelines violation.

Don’t touch WordPress core.

Thanks & Regards,
Gulshan
