[Mail app on tablets] Use 'Show split screen' enabled for default email app
- /e/ version: v3.2-A15-community
- Device model(s): gts7lwifi
## Summary
The screen of a tablet offers notably more space than phones.
Therefore I propose to set the default email app (Mail) for tablets out of the box in a 2-column view mode (Mail>Settings>General settings>Display>Show split screen>Always
**What does it bring?**
I assume that most users won't know this feature exists and it notably increases the usability of the default email application.
