Hello, what would be the best workflow/configuration to handle following objective(s);

1. have multiple global projects (applications); each such project having own version/release cycle (release/due date being longer timeframe); each project having multiple components (sub-)projects -- mostly for the purpose of organizing versions and releases
2. being able to specify "currently working tasks" involving tasks from multiple (global) projects or even projects not related to applications -- mostly for the purpose of organising "current work" and having overview of what's currently being done in one place.

Right now we leverage "Iterations" (each iteration is a version for one of our applications); it's configured on the top level (server/) and available for all sub-components (server/component1, server/component2, etc…) and this works very well for this particular application, it i

However, we lack a global view what would give option to plan and follow up with progress of task in the global scope of 1dev mostly focused on timeframe and not version (think "scrump" / "sprints").

It seems that "Iterations" would/could be better suited for the latter ("scrum") as it has timeframes and then use custom fields and boards view for releases but I'm not sure it's possible as for example it's not possible to assign due-dates and nicely track progress like in Iteration view.

tl,dr; / clue:

Possible solution: additional view in "Global views" akin to "Scrum" where we could see the current progress of all tasks (so columns would be typical State with Open, In progress, etc). Ideally with possibility to add swimlanes/grouping (by user/by project/by custom field)
