Ratatui: Build rich terminal user interfaces
Same for me, I would be much more motivated if there was something like textual for Rust. Given the capability of terminal emulators now I think Rust is lacking behind in the TUI field. Just checkout what can be done with something like notcurses

Terminal emulators that break from the traditional rendering approach?
On the application side of rendering, see notcurses, it is at the leading edge: https://github.com/dankamongmen/notcurses

Io Uring
The broader world probably knows him best for the terminal handling library Notcurses[1] and a lot of telling terminal emulator authors to get their shit together.
I’ve had his grad-school project libtorque[2] (HotPar ’10), an event-handling and scheduling library, on my to-read list for years, but I can’t seem to figure out how it accomplishes the interesting things it does.

Are We Sixel Yet
In XTerm, this (rightly) makes no difference. In Foot and Contour however, you still end up a line resp. a screen below where you started, if now with the correct horizontal position.
So it seems to me like what you want should work by default, except it doesn’t.
It should be possible to instead just treat the whole thing as a graphical overlay (by computing or directly asking for the character cell size, as Kirill Panov rightly admonishes me is possible with XTWINOPS) without touching the cursor; that’s what the “sixel scrolling” setting (DECSDM) is supposed to do. Then you can just manually move the cursor forward however many positions after you’re done drawing.
Except apparently the DEC manual (the VT330/340 one above) and DEC hardware contradict each other as to which setting of DECSDM (set or reset) corresponds to which scrolling state (enabled or disabled), and XTerm has implemented it according to the manual not the VT3xx[1,2,3]—then most other emulators followed suit[4]—then XTerm switched to following the hardware[5,6] (unless you and that’s what I’m seeing on my machine right now. So now you need to check if you’re on XTerm ≥ 369 or not[7]. If I’m reading the Notcurses code right, other terminals have followed suit[8].
Again, ouch.
P.S. It seems DEC had an internal doc for how their terminals should operate (DEC STD 070) [9]. It does not document DECSDM at all.

Contour: Modern and Fast Terminal Emulator
- you can also rectangular select like in vim, and then press either p (includes LF) or which joins the multiline clipboard text into a single line (removing LF's), that payed off a lot for output like `git status` and wanting to operate on parts of the output (files e.g.)
Have a look at the still young website's documentation here: https://contour-terminal.org/input-modes/#supported-text-obj...
for a more complete look of what you can do with the keyboard (normal mode) :)

GNOME’s horrid coding practices
Also, regarding VTE, the author of termite (discontinued terminal emulator) expressed similar concerns about the GNOME devs. Apparently, they have little interest in making the library useful to people not working on GNOME apps: https://github.com/thestinger/termite

Why are kitty and alacritty so popular? Where's the foot love?
I simply do not want to use anything libvte based. And that's what sakura is and termite used to be.

Show HN: Sixel-tmux displays graphics even if your terminal has no Sixel support
> https://github.com/thestinger/termite/blob/master/README.rst...
Wow, this confirms a lot of my impressions:
>> In 2012, we submitted a tiny patch exposing the APIs needed for the keyboard text selection, hints mode and other features. Despite support from multiple other projects, the patch was rejected. It's now almost a decade later and no progress has been made. There is no implementation of these kinds of features in VTE and it's unlikely they'll be provided either internally or as flexible APIs. This is the tip of the iceberg when it comes to their hostility towards other projects using VTE as a library. GTK and most of the GNOME project are much of the same. Avoid them and don't make the mistake of thinking their libraries are meant for others to use.
This is exactly why sixel-tmux exists as a separate entity!
> Yeah, I read the entire conversation and if sixel support lands in tmux upstream, it would indeed be good news.
I'll keep my fingers crossed, but right now, there seems to be a lot of good will. I will do everything I can.
