Mavericks and Tags

Is it true that the selection of tags is static in the new release? For example, I'd like to set tags based on variables I created or other metadata, but that does not seem possible yet.

Yes. I didn't implement dynamic tags as it's unclear how users are going to use them. If you want this implemented, then please provide specific, concrete examples as this will help me in the design of the feature.

Seriously digging the Tag support!

One thing I've noticed is that it's not possible to click the Show All Tags option. Is this something that can be added, or is it a limitation of Hazel being a pref pane?

Actually, there is a bug now where (a) not all tags, nor colors are shown and (b) clicking on the tags in the list dismisses it. The second one I've got a fix for. The first one I think I have a fix for but need more input. If you are experiencing (a) above, please email support with answers to the following:

1. Do you have iCloud enabled?
2. Have you edited your tags in Finder?
3. If so, did you do so before or after enabling iCloud.

I may have a test build so email me with the above and I'll see what I can do.
