Ad2. Okay, I haven't seen this anywhere. Thnx for the info.
Ad3. Even in the total darkness I can barely see anything on the screen. Black or dark-grey letters on the very dark backgrounds is a not an particularly wise or cool design idea. Even an amoled 6"+ screen size and full display brightness does not helps. The dark/night mode is still a piece of usability junk. Sorry, but it is as it is. Perhaps a bit different color palette would be a way better choice? Seems so.
@MartinBe please propose better colors, we’re open to any help. There are several related issues on our Github.
