Add a feature to change the default keyframe on a timeline to something other than opacity

I know this isn't really a new idea. I've seen other posts where people have asked if this is a current feature but most of the posts are 2+ years old and I'm just so baffled that Adobe decided to focus on changing the colors of the assets instead of adding a feature like this that would actually be useful.

An awesome feature that would save time would be being able to change the default "Show Clip Keyframes" from Opaticity to something else of our choice (for me it would be Time Remapping 200%). 

I can't imagine this is a difficult feature to add as I'm already able to change the Clip Keyframes but I just have to do it manually for every single clip. Having the ability to set the default would save me a siginificant amount of time. I know this feature has been asked for before and I would like to see it added. 

P.S. If you wanted to move the FX clip button back to the left side that would be dope because on long clips now I have to zoom in and out constantly everytime I want to select that button. Please someone explain the logic behind moving it to the left side of the clips.
