Persistent Storage feature: displays arrangement and resolution

I am technical enough to enable dotfiles and copy monitors.xml - cmdline version of what is described in the Persistence docs.

However I feel that many target users might not be at the edge of there skills, even following the nautilus directions.

• Proposal: create a 'save monitor resolution' toggle in persistence configuration.

The only reason I'd see not doing this if there are concerns about adding more options. The fact there is a network config toggle suggests this might be worth doing.

Thoughts? Too much of an edge case, or something that will help make Tails usable for more people who are less technical?

(edited for clarity)

p.s. yes I am willing to submit a pull request if this is something that would help.
