After the removal of the "Stop Activity" button in Plasma 6.5 (see bug #511058), all activities remain permanently visible in: The activity switcher (e.g., when using keyboard shortcuts like Meta+←/→), The “Move window to Activity” context menu. I manage many activities but only use a subset per session. Cycling through all of them is now inefficient and confusing. Feature request: Add a way to hide or exclude specific activities from these lists (e.g., right-click → “Hide from cycling”), without deleting them. This would restore workflow efficiency lost after Plasma 6.5. Note: This is not about closing activities, but about filtering visibility during navigation. Thanks
Seconding this. I do not really care whether the activity is actually stopped by the stop button (since it seems like it was not working, according to bug #511058), since when I stop an activity it is usually a long term thing (months). What matters to me is that only the small set of active activities (for current semester) are the only ones that I cycle through or are shown in the activity manager. Now my activity manager is just so HUGE in the panel that contains it... Maybe just put the button "Stop" back, but call it "Hide" or "Disable" instead?
The use case presented by Aldoo on the scale of months also applies to me, where labelled activities are representative applications saved in the launcher which were used for specific intents, which was why I filed #511354. Meta+Tab cycling now is alot more fraught than necessary. I understand that the term Stop is not as representative as the word Hide, but it did exactly as I needed.
Changing to wishlist, since this is a feature request. This may be more complex than it seems on the surface, I'll let the developers weigh in on this.
I absolutely support this "wish". Being one of the long-term KDE users who have refrained from using activities for long, I once learned to embrace them. I tried to live with the removal of the Stop button for some time now, but indeed it clutters my activity switcher with around 30 activities I have for different projects. In addition the Window actions menu "Show in Activities" has the same issue making it close to unusable. Looking at the announcements of the "Stop" removal and the overall discussion around Activities, I understand that maintenance reasons may require streamlining, but removing the "Stop" feature because essentially Snaps break it - I do not follow that (Look at how many are avoiding Snaps). Also the argument that it is not obvious what to do with applications open in multiple activities ... you just have to make a choice ... The stoppable (non Snap) applications associated with an activity now have to be stopped by hand when I pause working on the respective project. I have been a heavy user of suspendable activities, many who are used to project work will have been, and I support bringing it back. Fixing the newly-introduced cluttering of the activity lists is in fact a usability bug rather than a "wish" from the perspective of someone who actually knows activities.
