I used WordPad for certain text files, because it word-wraps differently from Notepad. Admittedly, that happens less than once a month. I will only slightly miss WordPad.

And according to that very GitHub, you have to downgrade Python to 3.10, or create a sandbox. I wish to do neither. For me, it's cleaner to create a whole virtual environment than a sandbox.

I'm old school. Programs should not requires system-level changes, period end of sentence. I miss static compilation.

Miniconda drives me crazy and the one time I tried to use it, it changed my default python environment system-wide. I have been increasingly annoyed by Python's having so absurdly many fractional versions, and its scripts refusing to work unless you supply them with version N.nnnn.nnn exactly. (Yes, I am exaggerating.) Here is the acceptable pace to make incompatible versions of a programming language: no more than every 2 years.

FWIW, this doesn't happen in KDE, only in XFCE4. I am ... mystified.

KDE has its own problems, of course. Nothing is ever simple.

Debian tends to be pretty conservative, and kbin is currently a pretty niche application that's only of interest to server admins. So, I suspect you're right. It probably wouldn't be packaged until a Debian Developer happens to be interested in it.

Name of web site is nitpicking.com.

You can request that kbin be packaged here: https://wiki.debian.org/RFP

If you're techie enough, you could even volunteer to be the Debian maintainer.
