Unintentional quitting user error.
Consider a confirm button when quitting as the command/ Q is quite close to Command /1
This will stop you accidentally quitting when meaning to get into standard view:
a number of times I have mistyped the Command /Q button meaning to hit Command /1, unfortunately unlike other commands there is no undo so I loose my history
A simple confirm box saying ‘do you really want to quit’ with a check box or just need to hold down Command/ Q for two seconds to quit.
