Description Christophe Marin 2018-11-08 16:54:33 UTC

Following a question on irc:

The identities settings window allows adding aliases for a given identity but there's no way to select one when writing an email.

Wish:
If there are email aliases for a given identity, allow selecting it in the From: field of the composer window.

Indeed... Now how to implement it...
No idea for the moment...

Comment 2 Mika 2018-11-09 13:51:07 UTC

A good solution would be searchable combobox, maybe?! Eg.: 

 + https://doc.qt.io/qt-5/qcompleter.html
 + https://forum.qt.io/topic/92105/qcombobox-filtering-by-typing

As this should help finding aliases even if an identity has a lot of aliases. Dropdowns still needs the user to search for an entry and they may not be sorted in a specific order.

Additionally, pressing enter should fill out "Reply-To" field, too, as in most use cases of using aliases the user wants to receive replies to the same address.

Another approach would be to let the user pre define the "Reply-To" default entry when adding a new alias via "Edit Identity" dialogue.

Later one can add "top 5 recently used" or "top 5 used aliases with receiver's domain" entries on top of the searchable combobox results. Similar to Libreoffice's Writer fonts dropdown menu.

Btw. here is an code example of a searchable combobox:

That's not *so* simple :) there are a couple more things to keep in mind, eg: removing the signature, not using the crypto settings...

True. This also includes allowing crypto for aliases. 

Enabling the searchable combobox and disabling crypto if non-linked keys are found is a start. This already helps a lot with using aliases.

Sure, ideally there is more to consider later on.

If I'm not mistaken, the "Redirect Message" dialogue already has the proposed functionality implemented. Except for "top 5 recently used" list all is working fine. The "Transport" dropdown might be a nice addition, too.
