Firstly, apologies if this is a wrong place for feature requests.

I have used Lotus Notes for quite some time and one thing I grew to love about Lotus Notes is "Send and File" option. How it works is this:
1. Compose you e-mail
2. Hit "Send and File" button
3. Choose what folder to save copy of the e-mail to
4. e-mail is sent to recipient
5. e-mail is saved in SENT mail folder
6. Copy of the e-mail automatically saved in the folder specified in step 3

This is very convenient when you manage projects and need to separate communication into folders and you can't make rules/filters for that.

Reproducible: Always
