Thank you very much for your question, Dimpsy!

We've put your need down and will add the filter condition goal later.
Could you please tell us what you would do when you filter out the tasks and projects with no goal? Add a goal to each, or delete the ones that are meaningless, or something else?

Thank you, Kassy!

I guess my workflow would go like this:

1. all single-step tasks will be in project "_do" that stands on the very top of projects, otherwise in "Next", grouped by project, single tasks without project would be displayed at the very bottom, while I use it often and want it at top. Project "_do" will have a goal, so all sorted single tasks will not show up on "no goal" filter.

2. yet-unsorted tasks will show up, as well as stray projects.

a) sort them into existing goals
b) create new goals for them
c) move them to "Someday"
d) delete them

I will decide it for each task/project personally.

This is not top priority, I just think it makes sense to be able to filter by every existing taxonomy, or absence of it. Including Goals.

@stefantsov Thank you for your explanation, Dimpsy!
It would be more orderly if every task is set with a project or goal, or those without project or goal can also be sorted in a certain filter.
We'll add the condition, but as we are now designing and developing new versions for all platforms, the need of adding goal condition will be set of low priority at present.
Please understand us.
If any new ideas or problems, please feel free to tell us.

Looking forward to see and use the new versions :)

@stefantsov Thank you! If any other ideas or questions, please just let us know.
