The other thing I think needs to be added are planet bookmarks. Control-F# sets one, Alt-F# jumps back to that planet.
I'm curious about this one, it seems like this is pretty duplicative with control groups. If you are wanting to go back to some particular planet, why not just set a control group on some key ship(s) there and use that? Having multiple sets of these sorts of groups seems less useful. Out of curiosity, did you mean Ctrl+F+#? F is already used for flares, in both screens. And control groups also work in the galaxy view, per player requests.
Well, there are only so many control groups. I usually organize them as follows:
1) Primary attack group. I can then pick sub-groups like fighters. (Which brings up the request: can you click on the right side icons to narrow a selection to just the one clicked on the right?)
2) Engineers/repair ships for #1
3) Temporary for whatever I need
4) Scout group
5) Colony ship/mobile builder group
6) Research vehicle group
7-0) Secondary attack group (usually mimicing 1-4 above with a second front)
The problem is, I sometimes or even often need to jump back to planets without control groups, for example, my home planet to change production orders or a planet with an incoming invasion force (with lots of free-roaming defenders) and so forth. Sure, I could make a control group 7-0 for those planets; that would work. But, I'd rather just have a planet bookmark.
I suggested Control-F# (Function Keys) because that's the "location bookmark" key (actually just F#) on all the other games I've played. You are using the F-keys for other things, so I suggested the modifier keys.
Cheers!
