Show HN: I made a tiny 2 MB screenshot tool for Windows (open source)

Working with LLMs, I've been taking more screenshots than in my entire life combined so far! I wanted a fast, handy screenshot and annotation tool for Windows, so I decided to write one. One thing led to another and it became a really nice screenshot tool, so I want to share it and open source it.

It is very lightweight (a single 2.3 MB exe) but it punches above its weight:

- capture a region, a window, or a single control (hold Ctrl) - arrows, shapes, text, numbered steps - mosaic / blackout to hide sensitive stuff - record a GIF, trim it, change the speed - shortcuts for almost everything

It's C# with NativeAOT and raw Win32, no WPF/WinForms, and no network calls.

I'm actively using it myself, so if you find any issues or have ideas, share them. The main idea is to keep it lean and fast, not bloated.
