I regularly add small jpg images inline to emails whilst helping customers, and I find I have to constantly open Advanced Property Editor and re-add the align option and set it to middle. See attachment.
Would it be possible to create a save button in the Advanced Property Editor so it retains what you have set? You could add a reset to default in case people make mistakes.
Or a config file that could be edited in Notepad ++ to include the options you want to use regularly.
