In post editor, show all buttons if there's room #1899
Description
The post editor has a row of buttons and the row of first-level buttons is responsive to viewport size. A couple items are behind a "tools" button and don't show up in the main row even if there is plenty of room. This is a request to show all buttons when there's room. "When there's room" is fuzzy; the question shows a viewport wide enough for all buttons (including tools sub-buttons) to fit in a single row, but we flow the groups into two lines at smaller widths. Maybe we should just promote those last two items and get rid of the tools button; there used to be more tools, but it's not clear that the remaining two deserve special status. On the other hand, I'm pretty sure we don't want three rows of buttons on a phone, so we'd need to check that.
Needs further analysis.
