Add new animations

[MKrabs]

Having some animations could make the app feels more alive and fn to use.

Things like:

• buttons visually getting smaller and "popping" after being pressed
• The result sliding into the "main" row
• cursor blinking

If you plan on adding animations:
maybe add a menu option to disable them, or even better have a range slider to choose the speed of the animation: going from 0 (none) -------- 500ms, with incremental steps (100, 250, 330)

I'm really bad at making animations with Kotlin, is there anyone who knows better who would like to help?

they are annoying. Why add them?

If you do them, I should be able to turn them off in some settings.
