Not sure I understand what you mean. My point is that the whole concept of the Editing on/off button is problematic. It's behavior (including presence or absence) is inconsistent throughout Moodle, which is probably what you are encountering. The proper way to address this would be to replace the button with an option menu that is more conveniently available throughout, e.g. in the user menu. It is true that the option appears in the Adminisration block but it is not particularly effective as the administration block can be set to not appear on certain pages or for certain roles. At any rate, you should probably open a tracker issue for that.

The 'Add a block' block is a fake block which is probably why it is not dockable. It only "exists" in editing mode. The "Blocks editing off" button appears when you are in editing mode. If you don't see it when in editing mode there is either something wrong with the theme or with the module where you encounter this issue. I've tried to work around such issues by moving the editing option to the user menu. See MDL-54653 for an initial proposal.

The Database activity doesn't currently support Course Overview. It requires implementation of a designated function in the mod lib.

Either use the admin purge caches option after such a change, or turn theme designer mode on. I typically use the former as theme designer mode on can be fairly heavy. With debugging on, the purge caches link appears at the bottom of every page. But I typically keep a designated tab in the browser with a simple page and I do the purging there, to save the time on page reload. And you don't have to wait for the page reload before refreshing the page where you want to see the effect of the change. hth

Mary, maybe the note is somewhat misleading. If I'm not mistaken, it should not be about disabling the filter, but about not using auto linking in the activity. If the activity uses auto linking and you disable the filter in the activity context, the entries would still be auto linked in other contexts, right?
