All thoughts, meeting notes, journals, blog post drafts... everything is jotted down in ST first. I even went as far as writing my own to-do list syntax highlighter[1] which is the main reason ST is always open, at home and at work, even though I mostly use VSCode and IntelliJ for coding nowadays.
I use PlainTasks [0] which is very similar to your plugin but also has a few keyboard shortcuts to toggle the item state. Using this with a watered down GTD setup has really brought a lot of peace in both my personal and professional life.
