Just tested the browse . Works beautifullyVersion 1.1516 is available on GitHub now and will be available in the Play store test program after Google's approval, mostly within a few hours.
This version will show searched and browsed messages faster. Please let me know if everything still works as expected. "It works fine" will be appreciated too!
Browse = download more messages from the email server on scrolling down. This is enabled by default and can be disabled in the advanced account settings.
I have also added searching for texts in local notes. I needed that myself ...
