Some more detail, as you requested:
Most projects I use have a Reference section and/or an Instruction section (or other similar related but less important sections for various purposes) which would need to be excluded from the tally but now can’t be.
The only workaround I see is to create a pair of projects (in order to isolate the actionable tasks in a project); no one likes that!
In some cases maybe that could be worked around by using the Project Description field for this other info, but that often isn’t the best way to go, as Asana’s own Templates demonstrate–they include non-actionable tasks in projects with otherwise only actionable tasks, so projects generated from those templates will be tallied incorrectly too.
Also, it would be greatly appreciated if feature removals are communicated in some manner.
