Todoist icon doesn't remember custom toolbar position
I didn't like the default location of the Todoist icon button in Thunderbird so I use customize toolbars and move it.
I have Lightning and Provider for Google Calendars installed which shows small icons in the top right bar and I want to put the Todoist icon there, it will let me place it there and works properly every time.
When I log back in the icon has returned to it's original position.
This only seems to seems to happen when I put it in this top right position, when I put it next to 'Get Mail' for example it is fine and remembers it's position... But this isn't where I want to put it...
I don't know if this is known bug but it's annoying!
