I see your plugin very useful, but I'm still not sure it can do what I need...
I import tags with "title to tags" plugin, so tags are sometimes in plural and not in singular like I need them to be. Titles also have letters with caps in our language, which are not accepted by tags widgets and should be replaced after import, therefore I need to replace tags and not all strings etc...
Could that be done in cron, cause I have same misspelled tags all the time.
Is that possible with your plugin?
