// NOTE: I'm not comfortable with the wallet being global data and this high up
|
|
// in the heirarchy, but there are 3 reasons for its current placement here:
|
|
// 1) There are some important threading issues where it comes to the password
|
|
// handling code, and a lot of it is done outside of the objects.
|
|
// 2) Different backends need access to the same wallet. so that it is not
|
|
// opened multiple times.
|
|
// 3) MainController is about the only thing that isn't deleted in between connection
|
|
// attempts.
