Edit / Remove tags

Currently there is a list to show available tags. Some tags are redundant or irrelevant but there is no option to delete them.

Start by locating the Android screen that displays the available tags and inspect how tag selection or management currently works. Done means users can edit or remove redundant or irrelevant tags from that list; the issue does not name a file or test, so the relevant entry point must be found first.
