For short term tasks (task-cache) I have ended up with essentially the same thing, just using *.md file + Notepad++ because of markdown syntax highlighting + snappiness of Notepad++ and I can then see it as a webpage using Markdown Viewer extension on Firefox.

For structured documentation of my projects + searching + writing notes down on the go via phone I am using Joplin.

For tasks to be done on a specific date I have calendar

For project management I have Redmine behind VPN so I can get on it from anywhere.
