Osu: Replace with "rewind" the "random" button text while holding shift

[Gabixel]

Describe the feature: I was considering the idea of making the text of the “random” button more dynamic: because of its very cool rewind function using the shift key, I suggest to change its text to “rewind” (or something like that) when holding shift, and turn it back to “random” when shift is released. This can be useful for new players or, in general, for anyone that didn't noticed this function (and it can be visually nice) because so far it has always been very hidden as a function, so only a few people use it.
Also, if you're considering adding a sort of "hint box" (like on stable) on the main menu, maybe you can add this thing to the list.

I think instead of pressing shift, long-pressing the random button by mouse would be better for mobile.

I was thinking about adding "rewind" button that lifts from under the "random" button after using it. It'd stay visible for 2-3 seconds after which it'd slide back under the "random" button. I guess it'll be more intuitive for many users.

Possibly pressing shift would also trigger it to slide up or change "random" to "rewind" text like in the post above.

May be better to poke @arflyte for this one, to fix the usability-without-keyboard issue at the same time.

Doesn't sound intuitive. I had no idea what is "rewind" in the first place. I'll figure out a better way to solve this.

Better implementation of rewind design not established yet.
