Inline templates / snippets

The Problem

I often write an email and need to insert a standard text snippet at a specific location. Inserting templates in Mailspring overwrites the entire email, which is not what I want to do.

I currently use Thunderbird with the Quicktext plugin and Gmail with the templates plugin, which both insert a template at the cursor position.

Proposed Solution

Allow snippets/templates to be inserted at the cursor position and not overwrite the whole email.
