I find it  very constructive in the discussion that everyone speaks its
mind in order to understand better what we are trying to accomplish
here. Based on that I think that there are some goals that almost
all agree.

G1: Simplify the Activities/VDs infrastructure for kwin and plasma desktop
in order to improve its maintenability

G2: Support workflows for groups A and B

G3: Improve the UI that Activities/VDs (MERGE) are presented to users

Based on G1-3 I think that we can see wayland as opportunity and not
as burden and improve the Activities/VDs area


----

Goals that are still communicated without reaching a "We all agree" state:

*G4: Support group C and not make them feel as a second citizen in Plasma
in comparison with groups A and B

so there would be some desktops fused with an activity some not.
the association could be 1:1 or m:n.. tough i see m:n would risk to
gather again a very confusing ui



Marco and Nate, concerning the UI approach I have in my mind the following

Group A:
    - a. Pager should work as now
    - b. VDs switching/handling (small view), needs probably something like the Activity Switcher
    - c. VDs switching/handling (big view), Present Desktops kwin effect is really nice

Group B:
    - a. Pager should work as now
    - b. Activities switching/handling(small view), I think the current Activity Switcher is just fine
    - c. Activities switching/handling (big view), Present Activities kwin effect would be really rice
 

Group C:
    - a. Pager, probably the user just needs to choose between A and B
    - b. Activities/VDs switching handling (small view): maybe just a column like the Activity Switcher is doing
    - c. Activities/VDs switching handling (big view):
There is already work on this :) from WorkFlow project in Plasma 4 era....

There is a chance that b(s) for all groups can be the same UI that changes accordingly and
c(s) the same kwin effect, there also some work on this area from : https://github.com/ajoshpratt/kwinOverview
