What do you use for your getting things done workflow? I just started using neovim and found the neorg (https://github.com/nvim-neorg/neorg) package which has a GTD module.
Keep it simple. My inbox only contains mails that require an action at some time. If I have done this action, I immediately archive the mail. I often mail todo's to myself so I have only one place for todo's.
If I have to do something on a specific time, I put it in my online agenda.
I have a separate setup for work and private, that's it. This works great.
ATM I use Todoist, but I'm wildly unhappy in using it. The only reason I do is that since it's a web-based UI, I can use it from my Windows box. Most of the halfway good GTD tools are Mac-only.
I've had a project going to build my own but admittedly have been somewhat dumb/lazy about it.
