This would be really useful. I quite often have tags I’ve typoed (like “pizza” and “piza”) as well as tags that mean the same thing (“ate pizza” and “pizza”). I don’t want to delete either tag, I want to merge them so they represent the same thing.

This will be really useful for future integrations. That means that if I’m currently tracking something using custom tracking I won’t lose that data when a relevant integration becomes available.

That is, assuming I tracked things in the right way/scale.

I desperately need this! I have foolishly tagged days with “alcohol” and “beer” and “wine” in the past and want to merge them all into “alcohol”.
