Aliases, multiple recipients, groups
Aliases work now, both for sender and recipient(s). Yes, recipients! To send a note to multiple recipients, just list them separated by comma (but no space), like this: “note to me,myself,ego,id”. As a special combination of aliases and multiple recipients, there are groups. They work exactly the same: “note to @owners OMG ooga ROCKS!”
If you want an alias added, note moeffju. Aliases can be regular expressions.
