In the upcoming version 1.12.0 the main feature will be the ability to send documents by email. I have already started working on it and here are the first effects.
This is very first version, and final solucion may look different.
The idea is that the user opens a preview of the document and selects “Send by e-mail” from the actions available for the document. The Keepmark will try to insert the content of the open document as content of email (when we do the action for textpack/markdown/html/md files), the other files within the document are added as attachments, where the checkboxes can be used to decide if they should also be sent.
