I'm wondering if we're working on the same thing. If you haven't seen my posts I suggest to look through them. In short: 1. stacked-commits automation (cannot skip writing context/why/verify sections) 2. Product specs (full ERD: https://excalidraw.com/#json=WT-oRUdyKBhAsDZJ3NwAR,WAbVgfO39XJ9zMkBxsM6ng) 3.

OK, so I get that you're trying an alternative on the metaphor that drag and drop uses. The metaphor is "pick up the item, move it, then drop it", but the implementation doesn't work well on mobile, so you made it modal. But for me scrolling feels like "pick up the item, move the rest of the world so the item around the item, then drop it". It feels very strange. As an refinement, I would keep the modality but add... - Source: Hacker News / 7 months ago

Excalidraw, an open-source digital whiteboard tool, has garnered a diverse array of opinions from the software development community and other user segments. Predominantly recognized for its simplicity and utility, Excalidraw has become a staple among developers, project managers, and other professionals who require quick and intuitive diagramming solutions.
One of Excalidrawโs strongest advantages is its open-source nature, making it a preferred alternative to proprietary tools like Miro. This open-source characteristic allows for significant adaptability and the potential for community-driven enhancements, which attracts users who appreciate the ability to tailor software to meet their specific needs. Itโs lauded in discussions of Miro alternatives, where it fits alongside tools like AFFiNE, Obsidian, and Logseq for offering customizable, flexible collaboration solutions.
Excalidraw's strength lies in its user-friendly interface and the simplicity of its hand-drawn style, making it suitable for sketching informal diagrams, mockups, and wireframes. This characteristic is consistently heralded by users who appreciate the tool's ease of use for quick diagramming tasks that do not necessitate the intricacies or learning curve associated with text-based or syntax-heavy diagramming tools like Mermaid. The illustration of complex system architectures, task flows, or even game development frameworks becomes straightforward, which is evident from its frequent use in technical interviews and software architecture design.
However, Excalidraw does have its critics, especially when compared to other more feature-rich tools. For instance, in enterprise environments and among system architects, there are preferences for tools that offer text-based diagramming or those superior in displaying change history. Some users find the necessity of operating within a browser limiting, as it may impede ease of access and fluidity when updating ongoing projects.
The collaborative capabilities of Excalidraw are frequently highlighted, particularly for remote teams needing to visualize and work on ideas in real-time collaboratively. This feature proves beneficial for a wide range of activities, from technical diagramming to educational purposes and beyond. It maintains a strong presence within developer communities, finding itself consistently recommended among essential tools for modern web development.
In forums and discussions, users note Excalidraw's utility for not only mere diagramming but also for enhancing productivity by integrating with self-hosted solutions, showcasing its versatility across various self-management and collaboration setups. The tool is appreciated for its role in helping individuals own their data and maintain privacy, an increasingly crucial consideration in todayโs digital landscape.
In summary, Excalidraw is widely regarded as a versatile, intuitive, and efficient digital sketching tool that fits well within the modern toolkit of software professionals. While it may not have all the advanced functionalities of its proprietary counterparts, its simplicity, open-source model, and adaptability have established a robust user base that values efficiency and collaboration without compromising control and customization.
