Feature Request: Persist state before exit

[leipert]

There are several potential things one could want to jump back to after restarting dry.

• Sorting of columns, I really like the sorting by status instead of container hash.
• Activated columns (if #48 gets implemented)
• Last screen, like monitor mode vs containers.

Maybe instead of persisting these could also be just commandline parameters, so that I can alias dry as I like it (maybe someone wants to start multiple drys with predefined settings)

Thanks for the suggestions!!

Going straight to monitor mode with a parameter should already be possible: dry -m

Persisting state is a nice feature, but to be honest it is a bit low on my priority list :) Imo it does not add a lot of value as compared to #45, #21 or expanding Swarm support, which is what I am focusing now.

Of course, if somebody else is willing to start working on it, I will be very happy to help with it and offer somer ideas on how it could be implemented.
