MarkdownClap is one of my pet projects, which could be accessed through this link: imballinst.github.io/markdownclap.
In the video, I showcased some features of the editor, such as:
1. Shortcuts (via keyboard)
2. Adding links
3. Copy-paste from spreadsheet source as Markdown columns
4. Convert Markdown table to set of text inputs
5. Fill columns with ordered number
6. Swap columns
7. Delete column
