Ability to group actions for minimizing/maximizing

[dbro]

Some flows have 10 or more variable initilizations (is this a word?). It would be amazing if we could group (and label the group) the like actions together and then minimize them as to not clutter the design surface.

The possibility to group actions will improve very much readability and maintainability of workflows.
