Use $EDITOR to edit a message
Would you be interested in having the feature whereby some key command (say ctrl+E as in qutebrowser) opens the currently written message in $EDITOR, allowing for easier editing of longer messages? I could probably implement and MR this if it is a desirable feature.
For longer messages, especially those containing markdown or some code snippets, this is a quite useful feature. Ctrl+E is already bound to Message Editing, so a different shortcut is needed for opening the editor.
Newcomer to gurk here, and this is the first thing I looked for.
This would be truly fantastic. Possibly a $PAGER view for messages too.
