Tag First Entry allows you to change the text if you do not want the drop down to say “Any”. You can disable that feature. If the user selects “Any” (or whatever you change the text to read) it will not filter the results based on tag.
Do not use () in any tag names. It will break things. Pro Pack tags are not going to be developed/refined further. I am focusing efforts on Tagalong and a new add-on pack that allows for arbitrary fields.
Tags in Pro Pack are too generic and too difficult to work with as a simple string format. The coding behind managing Pro Pack tags is a nightmare. If it weren’t for so many people using that feature in legacy installs I’d abolish it completely.
SLP4 will have better category support in Tagalong and the new add on pack will extend location attributes even further.
