Yeah, I forgot to put the /hsaves in there. Oops.
That popup could be created using dialogs and "loading" the hash table data into the dialog listbox and then adding a bit more information to the hash table including the checkbox information. It really wouldn't take much effort other than taking time to create the dialog. The only change to what you currently have is to add the checkbox values when you use /hadd and then only use the first token when you're using $hget() to display the correct spelling. The other thing you'd need changed is if you want to replace multiple words (like it' snot). What I gave you doesn't handle multiple words as-is. You can $replace spaces with another character (something you don't expect to see in the channel(s) you visit) to make it work.
If you do want to use something like that, I'd recommend trying to set up the dialog yourself and see if you can get it working. That part should be fairly easy as dialogs are all basically the same. They just usually take a lot more time to set up. That's really the only "hard" thing about dialogs.
Then, if you have any issues with it, post what you have and we'll help out.
