I mean, this works for the screensaver bit:
Code:
menu_item :main :Toggle screensaver :cmd_output :500 :quiet :test -e /mnt/onboard/.kobo/screensaver_old
chain_failure :skip :3
chain_success :cmd_spawn :quiet :mv /mnt/onboard/.kobo/screensaver_old /mnt/onboard/.kobo/screensaver
chain_success :dbg_toast :Screensaver on (Wallpapder Mode)
chain_always :skip :-1
chain_failure :cmd_spawn :quiet :mv /mnt/onboard/.kobo/screensaver /mnt/onboard/.kobo/screensaver_old
chain_success :dbg_toast :Screensaver off (Cover Art Mode)
It just moves the screensaver folder to screensaver_old back and forth. So that's a toggle right there! It's not an elegant solution but I'm happy with it.
As you suggested, I have screensaver images with text in them right now. But I'm more curious about the lock option.
If you (or anyone) can point me in where the pin settings are stored in the kobo filesystem I can write something up. Whether that's in an sqlite db or some config file I don't mind. I did my best to search the root filesystem but couldn't find anything.
