You're welcome! Thanks for writing such a great product :) I've got a bunch more little things I would like to add to make my life easier so I'll share them all.

Ok great, that's good to know that commands automatically get undo support :) This one definitely needs it since it is quite an intrusive operation, so I'll switch it to being a command instead. I also want to make a De-enumerator operation where you can specify a trailing string to remove, so this will need user input as well so will need to be a command.

Do commands have access to any extra java script libs? Something like string.js http://stringjs.com/ would be really useful!
