Edit menu too wide
When the edit menu is opened too close to the left or right of the page, the part that falls off the side of the page can't be accessed. Also it appears that it's not always appearing directly centred over the selection (not that this would resolve it if the selection is close to the edge of the page).

I'd quite like an option to 'pin' the menu eg. to the top or side, rather than having it float/[dis]appear..
IIRC, MediumEditor menu has a way to pin or have a fixed location for the popup menu. Need to test further. I think one alternative approach is to wrap the buttons so it takes up multiple rows instead of a single row stretched. I have some preference to have the popup menu appear in context, or close to the selection.
Aaaand this happens at the very top of a new document..
