[Request]: Optimize the UI for smaller screens

[matzipan]

Describe the request

First of all, thanks a lot for the effort you've put in the app. I use it daily and it's been a great experience.

Lately, I've been using it on mobile as well. There, the current Tuba UI layout can feel quite restrictive on mobile devices.

The screenshot below illustrates this. The spacing is a bit too generous, and link previous can end up taking more than half of the screen. Some simple optimizations should yield much better experience.

To test on desktop, all you need to do is just make the window narrow and small.

Implementation Details

• This follows the GNOME HIG.

My initial take is that changing paddings and heights based on breakpoints might be a big layout shift - but we already do a big one and the text wraps too so another one wouldn't hurt that much I guess.

I'll have to experiment with it and pass it through the designers
