Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

What is your go-to UI framework?
For small apps, I may choose a TUI (Terminal User Interface). Curses for Python is very lightweight, but quite low level and difficult to use for anything more than a very simple interface (if your app tries to draw outside of the drawing area, the app crashes, so you have to carefully manage every detail). Textual and asciimatics are both mature TUI frameworks that provide a higher level and more Pythonic way to create TUI's.

How to format output for a stand-alone display screen? Larger numbers, colors, redrawing the screen from the top left instead of printing a new line every time?
If you are looking for something more flexible that just printing to a terminal, take a look at Asciimatics and textual. Both are available from Pypi.

I'm making a notes app and am up to making an 'edit' feature, but have no way of making changes to a file's contents, let alone saving the changes and writing them to the file
Scroll down to the TUI example in the README, just above the documentation link: https://github.com/peterbrittain/asciimatics

ShyySH: a TUI connection manager for SSH
I have made yet another ssh connection manager with TUI, using asciimatics and tinyDB.

Best library for TUI (Text User Interface) and CLI (Command line Interface)
Personally I dig the aesthetics of asciimatics, it's quite handy and cross-platform.

Text UIs != Terminal UIs

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

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.
