Describe the Feature you'd Like

The plugin Buttons is deprecated and current plugin is recommended instead.

However it has some features that current plugin is currently missing, append template and prepend template.

The closest the current plugin has is Insert Into Note Button Action

However it requires explicitly specifying the line argument which is quite inconvenient. We need to be able to omit the line argument and use prepend or append instead to insert before/after the button itself
