I have started to use activities a bit, instead of Desktops.
Of course, there are advantages. Though within half an hour I encountered - what I consider - one bug and one question-mark.

I am pretty much a panel-less-person; if not a panel hater. So usually, my desktops (maybe in future activities) will do essentially without panels. Now what I found, is that inserting / removing a panel in one activity is replicated in all activities. So adding a panel in activity 3 adds a panel to all activities, etc. This renders activities rather useless for me, as of now, since I can't run activities with panel and activities without panel side by side. To me, this warrants a RFE.

Also, I see some crosstalk between activities: I had added a system tray in one activity, only in one, and then the icon, and only the icon of pulse audio became visible in all activities. This surely is a bug. If reproducible, needs to be waited out until after the next reboot; though as of now it is totally there in all activities and disappears when I remove the SysTray.

As far as I know, the panels are completely independent of activities. Only the content of the desktop itself is tied to activities.

Yes, that's what I was afraid of. Though then the whole activities serve no purpose at all to me, sorry. Not because I don't like them, I do, but they need to be fully independent desktops. I haven't been running panels for > one year, though at times they might be useful. If only, when someone else wants to use the machine, or there is little space.

I stand corrected w.r.t. the 'crosstalk' icon: the lonely icon that pops up on all activities, minus all the other systray, is the one for 'text snippets'.

The text snippets tray icon is probably Klipper. You could try filing a feature request asking for panels to be included.

Done. Thanks for your interest!
