re question 1: thanks for clarifying how to save changes e.g. by pressing ctrl+enter. but what i wanted to know is how we can exit WITHOUT saving any changes? in other words, how can i exit a tree (or card) i have done a bit of work on, without saving the changes i have made since opening it? if this can be done, it means i will then end up with the tree (or card) that existed before i started making additions/changes. now perhaps the system doesn’t work this way? fair enough if that’s the case … but would be great to know if it’s possible.
re restoring a backup (question 2), yes you have helped clarify this. if you decide to automate this feature at some point, that would be fantastic!
thanks again. i hope i have clarified what i meant in question 1. if not, let me know and i will try again (my writing skills certainly need improving).
