Aha, then strictly, you wouldn’t need it to be an applet, just a settings window like previews would do, -or- you could make it an applet without any presence in the panel (so no icon), only a settings section.
The show on your desktop would be just a transparent DESKTOP window in any case. What would you prefer?
Oh I did consider it but it will be overkill for something so simple.
But the biggest issue: most of conky is from 2015 when it was very popular. So pre python3 and loads of cool features never got updated. Maybe nobody cares anymore but THE coolest conky feature was showing transmission on the desktop: a list of torrents. Made in 2015. Needs a complete rewrite to be usable with the newest Ubuntu.
Conky is cool sure. But only a specific sub set of Ubuntu users wants to see cpu, gpu and memory usage on the desktop.
I would fully agree with you. With the recent demise of python2 security support, anyone who still uses python 2 based stuff are opening themselves up to a world of hurt. Stay well clear of anything python2 based.
… and yes 19.10 & 20.04 UB are now free of python2 - 20.04 repos has gone much further and removed many of the legacy python2 based stuff that hasnt had any maintenance for years.
