When reopening Mailspring it opens maximized instead of remembering previous window coordinates.
I would also expect the first email in the message list to be selected on launch, but no emails are selected.
with version 1.18 mailspring no longer opens maximised but it always opens at the same size, a small window in the centre of the screen. even when manually dragging the corners to create a new size, then closing and reopening, it doesn’t remember it.
This is a known issue on Linux under Wayland, unfortunately — the compositor doesn’t honor window position/size hints consistently, and doesn’t allow the application to move its own windows. (Though it can resize them, go figure…) I’m hoping improvements in Wayland and in Electron’s Wayland support get us closer to full window state save/restore behavior in future releases.
