My Locations - tag lookup when entering tags
When entering a value into a tag field it would be great if I could be presented with a list of tags I've already used enabling me to select the one I want. For example, I start entering the tag value "Racetrack" and as I enter the characters the field automatically presents me with tag values I've already used. Alternatively, present me with a dropdown list of tags I've already used. For me, this has three main benefits: firstly, it ensures that all my tag values are consistent i.e. I always enter the tag "Racetrack" and not something else if I have finger trouble. Secondly, it ensures that I don't end up with multiple tag values for what is essentially the same thing i.e. camping, campground or campsite. Thirdly it ensures consistency of search results when I use the filters to limit the view of my locations.
