Feature request: Remember window state on close

[superDuperCyberTechno]

Have you searched existing Github issues to see if someone has already requested this feature? Yes

Is your feature request related to a problem? Please describe. Every time I launch the application, I need to move it out of the way as it spawns in the middle of the screen.

Describe the solution you'd like Remember where the window was last placed and spawn there on next launch. Remembering size is also pretty important but it already seems to do that.

Already fixed by #173.

Will be part of the next version (first in a pre-release, so turn on beta versions if you want to get it as quick as possible).
