I don't know if these have been asked but I'll ask anyways. I like MicroB. It works just fine for normal browsing but there's two things that I really hate in it. There's no way to close the open window(s) if it's in portrait. Sure, you can end the task with the power-button and select "End current task" but other than that you can't just close the window.

The other one is the fact that we can't use the text-field in portrait either, though that's assumably by purpose (since we can't use portrait-vkb either).

Could these be fixed or is MicroB closed-source?
