This would be really useful to those managing IM systems.
Two considerations come to mind:
- I assume that this functionality would continue to be easily locked down to prevent users from switching as if its easy to do they will do it even if there is no need.
- I hope that the QR code scan method of transferring credentials between devices would still work with the multiple accounts as thats a real time saver for larger data collection projects
The concept is a great idea and would save time and avoid problems for a lot of people.
