I'm looking for a quick scratch note app for Windows that can stay always-on-top. I've been using Raycast Notes on macOS and love how it's instantly accessible for temporary thoughts during work sessions, but Raycast doesn't support the Notes feature on Windows yet.

What I'm looking for is something lightweight that I can keep floating above other windows while I work. Ideally it would have opacity control so it doesn't completely obscure what's underneath. Markdown support would be nice but not essential. I mainly need a place to quickly dump thoughts and copy-paste snippets without switching contexts.

What do you use for this on Windows?
