New iot menu or even default shell as user menu evtl. in python

[ulno]

The iot menu is quite popular, so we should think if we could do everything command line based with it (maybe offer simple shell escape right on front page). I also don't like that it is written in java script. There exists a prototype in python using prompt_toolkit in bin - after adding prompt_toolkit with pip install prompt_toolkit (inside of the it environment), you can test it with:

cd "$HOME/iot/bin"
python user_menu-python.py

However it was once very slow on the pi, should be tested on pi and pi zero.

Maybe also consider switch to textual (https://github.com/Textualize/textual) or something golang (https://github.com/rivo/tview) based?

This should probably lead to a new general TUI (text UI) affecting all commands.
