The Mermaid Popup plugin is a convenient addition to Obsidian, allowing you to display diagrams from various formats such as Mermaid, PlantUML, and Graphviz in a zoomable and draggable popup. With this plugin, you can easily view and interact with your diagrams without taking up too much space on the page. The popup is accessible through a customizable hotkey or by clicking an open button at the top of the screen. You can then use your mouse, touch gestures, or UI buttons to zoom in/out, drag the diagram around, and even close it when you're done.

The Sticky Notes plugin introduces floating note windows within Obsidian that mimic the appearance and behavior of traditional sticky notes. These lightweight popouts offer a simplified interface, separate from the main workspace, ideal for jotting down quick ideas, reminders, or temporary content. Each sticky note opens in its own resizable window with a default yellow background and can be pinned to stay visible. Access is available via the ribbon, command palette, or context menu.
