If possible, it would be a nice feature to be able to disable the glow effect on enchanted items. I read up a bit and it appears to be a tricky thing to do but would be great for like event items.

Example:
Enchant sword with sharpness, remove glow effect. At the moment this does not work, it will say "Success" but the glow remains.

Hi!
First of all thank you for the suggestions but I am afraid that's not possible. I have investigated the issue, and it looks that the Bukkit/Spigot API doesn't allow to unglow an item without removing the enchantments. I will add an error message instead of the wrong "Success" string.
Thank you

Ok thank you. Will I close the issue?

Yes, sorry. I couldn't make it work
