See, my idea would mean something like having 10 planets all being played under 1 account. Which atm would mean some kind of 'planet management' system, which would just attach 10 accounts to 1 username, with an option to switch between 'accounts' on the overview page or something.
Really though for the idea to work extremely well, it would mean a bigger change to PA. See below:

Basically the 'Overview' would become an overview of all planets, so would have all-round stats like "total gal roids", "total gal fleets" and such. Then for pages like 'Fleets', 'Military', 'Population' and 'Mining', the first page would take you to an overview page for that particular category.
Population, for example would be organised as follows: Galaxies would be lead by one planet and have one unifying government (which would represent the overview page, along with a 'master population settings control' for control over all planets), but individual planet population settings.
Mining would look like this:

And within the 'Mining' tab are tabs for each of the 10 planets.
On second thoughts, this idea is a bit too radical for quick implementation. We should just get rid of tag limits tbh.
