I built a clothesline for screenshots and notes on Windows

Description and use

Jemur is a Windows utility that places screenshots and notes on a clothesline overlay above the desktop, making them easy to find and edit.

Problem

When working on a bug or matching a design, screenshots and notes become scattered across folders, open windows, and notes, making them hard to find again.

Outcome

Jemur centralizes temporary screenshots and notes on a desktop overlay, reducing clutter and improving accessibility during development tasks.

Workflow

• Capture a screenshot or create a note using the default shortcuts (Alt+Shift+S, Alt+Shift+N, Alt+Shift+V).
• The captured item appears as a card on the clothesline overlay.
• Click a card to bring it closer to the user.
• Drag a card onto empty space to move it into the Discarded area, or drag it into an application that accepts files.
• Use the built‑in editor to annotate screenshots with pen, highlighter, boxes, arrows, and undo/redo.
• Configure retention period and other settings via the control panel.
• Close Jemur or let the line tuck away when idle; move the mouse to the top of the screen to reveal it again.

Evidence

When I am working on a bug or matching a design, I often need a screenshot for the next few minutes. I also keep small reminders nearby. Those references tend to end up in folders, open windows, and notes that I have to find again.

I built Jemur to keep them on a little clothesline across the top of my Windows desktop.

The line tucks away when idle, leaving the bottom edges of the cards visible. Moving to the top of the screen brings it back.

You can also drag a card into an application that accepts files. For screenshots that need explanation, Jemur includes an editor with a pen, highlighter, boxes, arrows, and undo/redo.

Jemur is written in C# with WPF and targets .NET 10.

The 0.1.2 release includes a portable EXE and a per-user installer for both x64 and ARM64. Every package includes the .NET runtime.

I would especially like reports about keyboard conflicts, display scaling, and multiple-monitor behavior.
