I don't think there's any way I can do this (if there is, please enlighten me).

I have big lists and it's tedious to be always scrolling down and up... Is there any way I can have keyboard shortcuts to move to next/previous planet on the list? Or any way to re-arrange the list to have more columns?

If there isn't, is it possible to add ?

I had in mind to create subfolder by A B C D ... or galaxy 1 2 3 ....

But this takes a while, first i have to finish the current development step

yeah, some subfolders by galaxy sound great to me when you have the time then
