my opinion on input and submit:
When after a user input document and need to get authorization (submitting),
I think is more practical if the authorize person can just click on a button in the current log in user ( input user) without a separate login. ERPNext then will display login/authorize dialog for the ‘boss’ ( userid/password ) to submit the doc.
I am sure you all have seen this on other apps that require frequent input/submit behavior.
thx
