There are 2 problems:
1. Some "Long" words like UTILIZATION it's cutting up to UTILIZA
2. If I don't like a tag which has been discovered like EP, LT, MAI ...etc and I want to delete them by clicking the X and then save the post whithout them it can't be done.
I have to disable this plugin , delete undesired tags, save, and then enable again the plugin if I want to .
3. What if "Ignore Capitals Percentage" is set to 0 ?
