Being a programmer, I created a todo list in the form of a text editor. Many, many shortcuts: links to files, outlook folders, azure, shortcuts, connection to the company VPN, basic text formatting. 6 months of excited coding. It looks great. I honestly don't know what I would do without him.
Some integration with tampermonkey and I have authentication on all the sites I use. Data is stored in pure files, indexed by sqllite.
My notes are typing-free. Images are turned into links and stored locally.
Dates are identified and placed on a calendar.
Desktop, made in C#, practical to the maximum.
