* Previewing message text in notification/widget: this is not always possible because the message text is initially not downloaded for larger messages.
* Executing filter rules: filter rules should be executed on the server because a battery powered device with possibly an unstable internet connection is not suitable for this.
* Widget to read e-mail: widgets do not allow user interaction, so a widget to read e-mail would not be very useful.
* Swipe left/right to go to previous/next message: swiping also selects message text, so this would not work reliably.
Since FairEmail is meant to be privacy friendly, the following will not be added:
* Show images without confirmation
* Show original message without confirmation
* Open links without confirmation
Confirmation is just one tap, which is just a small price for better privacy.
Background: this is because of the introduction of [doze mode](https://developer.android.com/training/monitoring-device-state/doze-standby) in Android 6 Marshmallow.

The error message *UIDPLUS not supported* means that your email provider does not provide the IMAP [UIDPLUS extension](https://tools.ietf.org/html/rfc4315).
This IMAP extension is required to implement two way synchronization, which is not an optional feature.
So, unless your provider can enable this extension, you cannot use FairEmail for this provider.

You can start searching for messages on sender, recipient, subject or message text by using the magnify glass in the action bar of a folder (not in the unified inbox because it could be a collection of folders).
The server executes the search. Scrolling down will fetch more messages from the server.
On some devices, where there are lots of applications competing for memory, Android may stop the synchronization service as a last resort.
Some Android versions,

**(23) Why do I get 'Too many simultaneous connections' ?**
The message *Too many simultaneous connections* is sent by the email server when there are too many connections to the same email account at the same time.
Possible causes are:
* There are multiple email clients connected to the same account
* The same email client is connected multiple times to the same account
* The previous connection was terminated abruptly for example by losing internet connectivity
No app, except maybe file managers, targeting Android 4.4 KitKat or later should ask for storage permissions because it would allow access to *all* files.
