Prompt how to allocate Tasks filter without labels?
Unfortunately, it is not possible to filter tasks with no labels right now. You can vote for it here: https://todoist.com/Vote/show/6108/.
I do not understand why this critical gap in functionality is not yet updated. When I add tasks on the fly it is a critical part of my workflow to maintain task labelling and clean up tasks with no label/tag. If you use filters and label/tags and there are tasks buried that are not labeled then the process is flawed. I do not understand why a syntax can not be created that looks for Label=null?????????
