Right now, every time you browse to the planets page, or refresh it, it’s sorted by planet/system.
I’d like to be able to set a new preference for the default planet sorting.
Some players like it to be sorted by OB rate, total built, size, population, bonus, who knows? But now you have to redo that every time.
Can we get a personal default sorting option? 
@I_like_pie - if your dumping all your ideas in feature request: pick up these two as well!!
I was about to suggest something along this same line. Nice to see someone else has been thinking about it too.
At least twice this past week I’ve sorted planets to build on empty planets, clicked on one planet and constructed buildings, then went back to the previous screen and ended up OBing a planet because the planet list had defaulted back to the unsorted list. Quite annoying and costly.
I’d like to see @Hala’s idea of players being able to establish a permanent sorting default, OR to be able to have another custom sorting remain in place until a) the player is logged out of the game or b) the player resorts the lists manually.
I like this option. Maybe we could have a preferences menu for this sort of thing. (Pun not originally intended!)
