On a similair vien the auto continuation of the aid research 'building' (or other 'buildings like it' is driving me bonkers. The worst is with station garrison. You tell a planet to do that only to realize a bit later that the planet now hass all 22 of your legions garrisoning it instead of the 3 or whatever that was your intent.
Do they auto-continue now? I didn't realize that yet. That was much requested by quite a lot of people (not me), but at least to me it was clear that once it's implemented the other fraction (of anti auto-continuation advovcates) would complain ...
I personally belong to the people that like timed projects so that you get notified fro time to time to look after your planets. That's e. g. important if you researched some terraforming techs and now don't want to go through every planet manually to check whether you have to build that.
The best way would be to have a per planet setting for auto-continuation of projects yes/no.
