Feature Request

Is your feature request related to a problem or unsupported use case? Please describe.
Recently, the support of latex has been added into the Ashley editor. Currently the only manner to add a latex block is to use the key $ or the shortcut Cmd + Shift + M. This is convenient to add quickly a latex block but for "basic" users this could appear like an hidden feature.

Describe the solution you'd like
Add a button to add latex block within the editor toolbar.
