1) I find that when I travel from home to camp, or visa versa, I cannot "connect" to the server at that location unless I go into preferences->manage servers, and choose the radio button for the location (under found or saved). Should it be automatic?
This behavior is correct. Squeeze Ctrl always tries to connect to the last used address first, regardless what server discovery finds. If the connection fails then it will ask you if you want to choose another server. For the vast majority of cases, this can speed up the connection by a few seconds since server discovery takes 2-3 seconds.
One way around this is to assign the same IP address to the servers at home and at camp.
You don't have to go into preferences to change the selected server. Just tap the header in the blank space between the icons where there's a little "down" arrow.
2) I use sync alot. Example - if I am working outside I might sync "garage" with "outdoor", and maybe "workshop" too. But, I want to make sure I unsync "outdoor" when I am done so I am not playing the outdoor speakers at 11PM if I am in the garage or basement. I leave the amps or booms on. I would love to see either/both:
a) an unsync all. maybe on the manage players menu selection (at top or bottom of list of players)
b) from the pullup at the bottom (between volume and rew/fwd) a selection for sync. I don't use repeat, shuffle, etc.
I can navigate to sync and unsync but it's alot of operations. To be able to sync or unsync all/individual on the same page would allow me to sync, say 3 by sync all (syncs 5), then unsync the two I don't want.
A sync/unsync all button is a good idea and shouldn't be too hard to add, though it wouldn't save you any taps in your specific example.
Proposed method: 1 tap on sync all button to open menu of players to sync to, 1 tap to choose the player to sync to, 2 taps to choose the players to unsync, 1 tap on the unsync button = 5 taps.
Current method: 3 taps to choose the players to sync, 1 tap on the sync button, 1 tap on the player to sync to = 5 taps.
Of course, I get what you mean, and if you are syncing more players it will save taps.
c) even better would be sync favorites (common sync profiles), but now I am getting out of control
Sync favorites is an interesting idea, but the implementation would be a lot more involved and not something I feel like tackling right now, but I'll put it on the back burner.
BTW, you can double tap the space on the bottom between the volume and playback buttons to open the Player Manager.
