Currently, I'm design a stock market widget. The widget is pretty much analogy to GMail widget as both of them contains multiple profiles.
GMail widget is giving user to choose 1 out of multiple folders (Inbox, Outbox, ...)
Stock market widget is giving user to choose 1 out of multiple watchlists.
Step 1 : Let user to choose
Step 2: Show user what he choose. The choice is fixed and can no longer be changed.
I was wondering, why don't GMail widget designed in such a way, once the widget is placed, user is still having ability to switch (through left/right swipe?) among different folders? Is there any technical reason, or UI/UX design consideration behind?
I refer to many stock market widget in current Google Play Store. I realize, none of them provide ability to let users change watchlists on the fly, once the widget is placed.
I was wondering, what is the real reason behind such design?
