Just as a side note: If you swipe down from the status bar with two fingers, you open the entire quick settings. This saves you at least one swipe

I was searching for a quicker solution for switching profiles too.
I hoped that the currently useless digital assistant button (Home) via hold/long press on default android, could be used by the graphene os devs to open up the user profile switch menu.
I get this is UI and security/privacy comes with it's inconveniences, but this it the part where I lose the most time during daily usage.

Adding an intent would suffice, while it's "easy" to swipe down with the two fingers on top + tap + tap, it would be even easier to be able to simply click a widget/shortcut.
Ideally an intent with optional parameters, for example launching the activity would open the user selection dialog and giving it a parameter with the account name would launch it directly.
