QubesOS Usability & cheatcodes a live command-line?

[081704397843209478]

Apple's OS is based on Linux.

Google's OS is based on Linux.

But nobody see's Linux as a important (endpoint) desktop OS.

So there is nothing to expect that the usability might change in the near future, way from the "geek desktop OS"....

But it is true that excellent usability is not the same like an engaging on boarding of the newbies, to get the basic tasks done.

David Adams is right, with the basic commands the productivity get boasted a lot.

How I can see and use a QubesOS command-line on a fixed position on my screen, so I can every second use command by this command-line tool - so speed up the Qubes OS productivity?

How I can define my own commands (which fit better to my tasks and by the way I will then remember them much better)?

Knoppix uses his own cheatcodes...

the brain allows to download and upload hotkeys...

very cool stuff towards a better usability :-)
