I also use sublime for managing todo and IDE for coding as my work repo uses custom tooling for build and autocomplete which only supports Visual Studio.

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.
