Congratulations on the launch! I downloaded Obsidian for the first time last night and spent all morning customising it, so the timing for me couldn't be better.
Quick note, on the website the download button for MacOS is delegating to "https://github.com/obsidianmd/obsidian-releases/releases/dow..." despite the button saying "Version 1.0.0", I believe it should be "https://github.com/obsidianmd/obsidian-releases/releases/dow..." instead?
