Just what the title says - I can not switch to another app and back to Gmail and return to the email I was looking at. Gmail doesn't show in the open or recently open apps lists. I assume this is across all devices and flavors of Android because it happened the same way on my OG Droid. It's not a huge deal, but it would be cool if I could look up an email and switch to the calendar and then back to gmail without having to run the search for that email again. Even the iPhone's weak multitasking lets me do this.
