Hide "Share Note for Obsidian" watermark

[ZeroMB]

I don't know if it's right to ask this, but if the user could remove the "Share Note for Obsidian" bottom watermark, this would be very nice for a clean experience. Maybe by default it's enabled, but the user had the option to toggle to turn it off.

And for the theme toggle, the website will automatically adjust to the device's theme. If the device is set to Dark mode, the website will open in Dark theme. Conversely, if the device is in Light mode, the website will open in Light theme.
