reduce toast usage

[zuevval]

There's a heck of toasts here and there in the app, so when I switch controls quickly, they lag severely. Now there are even more of them after introducing columns flips.

I propose a (partial) solution:

• Instead of toasts, announce the column flip event by an accessibility service + write numbers on each dot for sighted
• practice: replace toasts with announcements, too, + animate "next" button (red/green glow on answer)

First done. Here's how it looks like (GIF animation).

or maybe use a thinner font? Compare:

left to right: default, Sans Serif light, Sans Serif thin.

I'd rather use Sans Serif Light

So i have thought of two options. First is to set up an animation for the "next" button:

However, it looks strange when on-the-fly checks are turned on. So I have implemented another thing - an animated background

This required unsetting the Braille dots' background with the vertical line, but I suppose it's not important because now dots have numbers.

another idea, maybe this is better?

Sans Serif light looks better to me

Animating all background I like more

@winter-yuki, I thought that animating the whole background may be unpleasant for eyes, especially after you use it for a while. Try to download the APK from the last workflow and practice for 5 minutes.
