I use a lot of tags to describe my posts and so that the 'Related Posts' plug-in works effectively and relates truly related posts. But I fear that I use a different tag for the same thing such as 'audio' or 'music' or 'sound', which ideally should have been any one out of these three, but now that they are 3, they don't get related.
Is there a plugin or any other way to see all my tags on the 'Write Post' page in the Dashboard? This feature is present in Blogger. That way I can have a look at my tags and select the relevant tags instead of adding new ones each time.
