+* *Rich text editor*: besides that very few people would use this on a small mobile device, Android doesn't support a rich text editor and most rich text editor open source projects are abandoned.

 * *Widget to read messages*: widgets can have limited user interaction only, so a widget to read e-mail would not be very useful. Moreover, it would be not very useful to duplicate functions which are already available in the app.
 * *Badge count*: there is no standard Android API for this and third party solutions might stop working anytime. For example *ShortcutBadger* [has lots of problems](https://github.com/leolin310148/ShortcutBadger/issues). You can use the provided widget instead.
 * *Switch language*: Android is not designed to change the language of an app and on recent Android versions it even causes problems. So, better fix the translation in your language if needed, see [this FAQ](#user-content-faq26) about how to.
