This might be a stupid idea, but I feel compelled to share it.

As an adolescent, I hated the DS, I felt it was too stupid and gimmicky, but when the Sony Vaio UX came out, I lusted after that and wish I could have afford one and I liked how it had a full keyboard, but it wasn't until some time after the "New 3DS" was discontinued I thought of designing a portable with a Pi zero in it, so I looked around for something I could find pocket sized, so I got a VHS tape and made a hinged cardboard mock up of a portable system, but I noticed my thumbs would be too far apart to thumb type comfortably, so I thought "oh, I could just have a second screen with a stylus where I could write and the software could turn it into unicode and if I can't I could just draw messages and send it as a 1-bit PNG via wifi and I realized that was already invented. But today I see some of my old games like Deus Ex and thought of having a external UI for the menus on another screen and peek and poke the game internally from the external screen menu.

In addition to the 21:9 monitors, there is a lot of quality of life being able to use a secondary screen. There are also 16:18 screens being sold on amazon for vertical workspaces and this could scale to desktop. So I think in order to have screen scaling UIs, it would be wise investing in a bespoke UI libraries like somebody might have a secondary 9:16 screen or a 4:3 one and said UI libraries might make Linux native more viable to try again, but I don't know.

I don't know if this will ever be implemented, (probably not) but I felt compulsed to share this.
