What is the currently accepted utility for deleting undesirable records from a plugin? TESVGecko? Something else? I have a few dirty edits I'd like to clean up but don't want to make a mess of things in the process.
You can 'clean' a plugin manually with the Creation Kit and know you're safe. File > Data > Set YourPlugin.esp as "Active" > Details. From there, select forms to remove/Ignore with Delete key > Click OK. When you save the plugin, the "Ignored" forms will be removed.
Note: You can't "Ignore" GRUP entries, but they'll be automatically removed if they've no children
When TES5Edit arrives, it'l be as easy as http://i.imgur.com/4x4J8.png followed by R-Click > Remove "Identical to master" records. Gecko is still in alpha/beta, so I'd just use the CK for now.
