Is there a way to delete theme tags from a table? The default example theme (something about “Improvements of accounts”) is always popping up annoyingly and I cannot seem to remove it. Same with themes we deem irrelevant and want to delete again. And finally editing themes does not seem possible either. is it possible to change the color of the theme labels, they all default to dark brown.
