I find it amusing how this seems to be a very common response to this sort of Ask HN question. If you want something right, you gotta do it yourself!

Here's mine: https://github.com/upvalue/meditations

It also supports habits and notes, but in mine the tasks and habits are combined. I'd like to go further like you have in combining the notes and task interfaces (right now it's basically two separate apps that happen to be in the same codebase + database).

I like it. I use both approaches, so there's individual task/habit/notes modules like you have that let you dive deeper and edit and tweak things, and then the general dashboard which is more of an overview that combines them into one and lets you get common tasks done quickly. The dashboard is date based (defaulting to today) while the modules aren't.

I'm sure your app is quite more user friendly and inviting ;) but I thought I would share this one. It's kind of cool to mess around with if you're a command line nut.

A habit tracker + to-do app? It's one of my side projects, too
