'liquid button' should imply 'button mash'

liquid button -> button mash

I’d think an alias would be better.

@Zharkaer  
‘Liquid button’ is only for the “newer” lighter-toned one. Aliasing would put both versions together.

@Dragonpone  
The tag’s kind of useless though, considering very few people use it. And after all, we don’t have a separate tag for Sunset’s color scheme after Rainbow Rocks, do we?

@Zharkaer  
Sunset had a color change? Maybe I should start paying more attention to the movies.
 
After checking though, Button’s change is much more drastic:  
 
I know you were only using Sunset as a hypothetical, but her change is very minor in comparison. It also might help to keep the tag around for filtering purposes, so people who don’t like the color change can filter it out.
 
I will admit though, I didn’t notice it was one of the ‘created and mostly tagged by one or two users’ tags, but I don’t see any problem with keeping it around in this case. Unlike other tags, it wouldn’t be as easily replaced with a complex filter.
 
I don’t have any real attachment for the tag, but I also don’t think it’s completely pointless.

Implication done. Leaving open in case there is another good point towards aliasing.
