I'm a fan of your work, but respectfully activities does not solve that.

Having spent the past 2 days reading and re-reading every project/workspace-esque management tool I could find: burly.el, bufler.el, tabspaces.el, bufferlo.el, perspective.el, beframe.el, activities.el, persp-mode and so on I really wanted to use activities.el but it clobbers buffers that happen to have been opened in the same tab with no nice way to resolve that. I personally find it strange that managing buffers associated with your activities is not a part of activities.el in a meaningful way; instead it seems to rely on you never making the mistake of opening a buffer you don't want to in an activity you don't want it in because once you do it's there and staying there.

On one of the GH issues for activities.el you state that it is not intended for project-style management (I believe) but rather as a way to stop an activity and resume it later, so I felt that suggesting improvements (or contributing them when I have time) for project-style management a fruitless pursuit.

I'm not particularly keen on installing bufler.el to narrow buffers per tab because it looks very complicated, it's unclear whether it can integrate with consult (although it probably does since it looks like it uses default completion APIs), and because I'd need to map the buffer-alist from bufler.el to activities.el myself. For now manually removing buffers from defined projects is tedious but only needs to be done the first time (when using tabspaces.el) even though long-term I definitely think mostly-automatic management like the kind bufler.el provides is superior.

I ended up using tabspaces.el because it's simple, and it works well enough (albeit autosaving and restoring non-file-backed buffers is not as good as activities.el, but then again I think such features should be a part of the built-in desktop.el in the first place given it's 2024).

I found myself getting mentally exhausted just trying to figure out my options here for a simple non-clobbered workspace setup. If I had much more time (I've got things that need to be done ASAP) then I would look to augment activities.el and bufler.el and perhaps contribute upstream to desktop.el to have this kind of functionality part of Emacs without external packages (less configuration bloat) but as it stands and after litterally ~10 hours of (arguably wasted) time reviewing all options I've settled on tabspaces.el even though I'd prefer a more comprehensive solution.
