Rotating option is coming (already coded but just not added an option button).
Now that you can go full screen the mini-map on a big 1920x1280 or whatever resolution makes it maybe slightly smaller than ideal, so we may add some size options to the mini-map some time. Its only become apparent with the bigger res but I agree. We'd probably make an option 'auto-size' to screen resolution on by default, so it'd size as we think it fits best, but also with custom options if you want to override that also. There's plenty of options to add, we've got all the custom key binds to do too
