There are a few outstanding questions regarding the control of the flow of tasks within projects (parallel, sequential etc). It would be nice to have an update:
Planning Capabilities
Features for managing the forward flow of all different types of actions and of sub-projects have already been built in, generally speaking, except that the app still does not have the capability to let users pre-plan (pre-mark) actions within “inactivated” (sequential) sub-projects - only within “already active” subprojects. Is this recognized and will it be amended?

Simplicity of User Interface
It might be argued that the user interface could be simpler and more consistent, easier to understand and use. For example there could be one universal toggle type for all kinds of actions and projects and one universal visual indicator type for all of these. Is this something you are planning to address?
Possible Bug
A possible bug has been reported but not commented on, concerning the fact that the sequential setting for projects seems to affect different subprojects (and projects) differently. Is it a bug or am I missing something?

Manual inactivation of entire projects
Useful and part of GTD. Is this on the roadmap?
