Portals allows you to route jobs within Switch, without a direct connector. You can use this to better structure flows for readability, prevent crossing connectors and duplicate logic, and easily pass jobs between flows. Portals also makes sharing bundled flows much easier, as you don't need to relocate non-automanaged folders every time you import a flow on a new system. This bundle contains two apps: an incoming and an outgoing portal. Portals are multiplexed by channels (which you select in the script) so you can have multiple sets of portals within a single flow.
Portal is nice and easy to use and the apps are working quick and easy in switch.
Portals is really smart and takes care of spaghetti in my flows with aplomb.
Recommended for everyone.
