Yes, of couse, but i need your help, because i have to know how the manila config-files are called on your device.
'change tab order' works on any devices.
'change date format' is language specific.
You have to search for a manila-file with the following content (but in your language):
<?xml version="1.0" encoding="utf-16"?>
<xliff version="1.0" lang="en-us">
<file datatype="plaintext" original="Home">
<source>MMM d, yyyy</source>
