Don't know if this is a known issue or not, but when tagging images, if I click on one of the buttons in the My Tags section which has certain punctuation characters (eg. brackets or slashes) then it searches the tag rather than applying the tag to the image. Is there any chance this can be fixed?

It's a known issue, but a very low priority as I don't have the JS knowledge to fix it. Maybe we will be able to fix it in the near future, but don't count on it. The same goes for clicking an already selected tag.
