Let's start a separate topic about this QoL improvement.
Have a look at this request:
https://openxcom.org/forum/index.php/topic,7715.new.html#newI would like to extend it a bit in the way that it should be possible to switch bases and do the same operation type in them too. For example, when I see research popup about research done, I can assign scientists to new project not only at this base but at other bases too. Same for manufacture.
Granted, it may not be used very often but there is one case where it is needed. At the mission debriefing it may complain about insufficient transport inventory and propose to manufacture them at the same base. However, it may happen that manufacture takes place at other base and I cannot do this within debriefing. I have to end and then set up manufacture manually. Not very often occurring case, I agree. However, adding ability to check other bases production is not harmful since default will be current base anyway.
Another option is to show base related popups outside of bases as a global operational view. For example, when user click "C" in geoscape they are given a list of research at all bases. We can use something similar when research is done to assign research at any base.
